Bernd Eckenfels commented on VFS-142:
-------------------------------------
Hm, I don't see really a difference. Both methods will clean the value and keep
the key (ThreadLocal instance) (weakly references). The Key does not contain
references to VFS objects. In fact remove() seems to be a bit more efficient as
it would not create the ma or insert the key if not present (anymore).
> Clear ThreadData after all streams are closed, fixes a memory leak
