* The cache file datablock is now evaluated as part of the dependency graph, creating/freeing the Alembic file handle matching the current frame. Modifiers and constraints depend on this evaluation. * Cache file handles and readers now only exist on COW datablocks, never the original ones. * Object data paths are flushed back to the original for the user interface. * The cache file keeps a list of all readers associated with its handle, and automatically frees them when the handle is freed. This kind of sharing of data across datablocks is weak but we have no better mechanism for it.
