特定の条件下で処理がフリーズしたように遅延する件は最新版の更新で改善されていることを確認しました。

ハードウェアが古いから無理だと回答していた奴いたけど・・・
ちゃんと調べて回答してないって事まるわかりだな・・・。

まぁ、こっちはちゃんと動けばいいけど・・・
いい加減な回答でバグレポートを閉じるのだけは勘弁して欲しいな。

* Fix crash when changing and using between layer and other brushes in dyntopo
　Layer brush would not invalidate the layer_disp arrays in dyntopo mode,
　checking only for the existence of the array. This means that if a tool
　resized the node due to topology changes, the layer brush code could
　index (and write!) out of bounds in the array. Solution is to invalidate
　the layer data prior to each stroke in dyntopo.

* Fix action-editor crash transforming gpencil and masks
　There were 3 bugs with both data types
　- using freed memory while sorting.
　- sorting failed in some situations.
　- scaling allowed multiple items to be on the same frame.
　Replace this with a simple sort + de-duplicate, taking selection into account.

* New Corner Pin node: uses explicit corner values for a plane warp transformation.
　This was suggested by Christopher Barrett (terrachild). Corner pin is a common feature in compositing.
　The corners for the plane warping can be defined by using vector node inputs to allow using perspective plane transformations without
　having to go via the MovieClip editor tracking data.
　Uses the same math as the PlaneTrack node, but without the link to MovieClip and Object. {F78199}
　The code for PlaneTrack operations has been restructured a bit to share it with the CornerPin node.
　* PlaneDistortCommonOperation.h/.cpp:
　　Shared generic code for warping images based on 4 plane corners and a perspective matrix generated from these.
　　Contains operation base classes for both the WarpImage and Mask operations.
　* PlaneTrackOperation.h/.cpp:
　　Current plane track node operations, based on the common code above. These add pointers to MovieClip and Object
　　which define the track data from wich to read the corners.
　* PlaneCornerPinOperation.h/.cpp:
　　New corner pin variant, using explicit input sockets for the plane corners.
　　One downside of the current compositor design is that there is no concept of invariables (constants) that don't vary over the image space.
　　This has already been an issue for Blur nodes (size input is usually constant except when "variable size" is enabled) and a few others.
　　For the corner pin node it is necessary that the corner input sockets are also invariant. They have to be evaluated for each tile now,
　　otherwise the data is not available. This in turn makes it necessary to make the operation "complex" and request full input buffers,
　　which adds unnecessary overhead.

* Fix T39104: 2 clothes on a collision object cause crash
　This was caused by static variables used in plNearestPoints().
　For now solved by making the solvers allocated in the stack,
　seems no noticeable affect on the simulation speed so far.

* Fix T39152: Blender crash when duplicate mesh with hooks and laplacian deform.
　We can't simply dupalloc cache_system (LaplacianSystem), it has quite a few allocated data we'd need to dupalloc as well,
　not to mention (nl) context... Much safer to just set it to NULL in new copy imho!
　This commit is to be backported to 2.70 release!

* UI Tweak: Add a convenience button for switching to Bone Constraints Tab
　To reduce user confusion, we were already presenting users with an error message
　when they tried to edit constraints for bones from the Object Constraints tab.
　This commit just makes things more convenient by adding a button which takes
　users to the right tab when clicked.

* Fix T39180: Particle with fluid physics unstable.
　Fluid particles use the particle system's bvhtree structure, which is a
　runtime BVH tree. This was not reset properly on copying objects/psys,
　which lead to concurrent access in threaded depsgraph updates and memory
　corruption.

* Fix T39383: Blender crash when renaming bone in outliner (weight paint mode).
　Outliner rename callback is supposed to activate affected element before actually renaming,
　but for bones this was not working because the function used to activate the object explicitely
　ignored ID_OB case! Added a bool flag to allow handing this case without (possibly) breaking
　the other usecases.

* Fix T39318: Blender 2.70 crash when I link an asset
　Issue is a regression since threaded objetc update and caused
　by the fact that some objects might share the same proxy object.
　It's all fine but object_handle_update() will call update for
　a proxy object which screws up threaded update.
　The thing is, proxy object is marked as depending on a scene
　object and such a call makes it so the children objetc is
　being updated.
　This is really bad and depsgraph is to take all responsibility
　on updating the proxy objects.
　So for now used a simple solution (which is safe to backport
　to 'a') which is skipping proxy update if the scene update is
　threaded and based on the DAG traversal.
　There are some still areas which calls object update directly
　and for that cases proxy object is still being updated from
　object_handle_update().
