Actually, I wouldn't be sure about that either. There is a TODO comment, but
nothing implies that this is the case.

One thing I do know fairly certain is which surface gets b0rked. One of the
traces I made shows the bogus addresses inside surface passed to
IWineD3DTextureImpl_Release, which are the most likely place where the
corruption happens, and incidentally, the cleaning of that structure is the
last thing that happens right before segfault. I have yet to trace the surface
since its creation, rather than watching its destruction.
