This sounds like a logical explanation. The cache manager would need to
look for open, unlink()ed files on unlog and remove them on the server.
The hard thing is that the user might still be allowed to read them
(system:anyuser with read permission) - probably complicated to solve
(if possible at all).

Any workaround involving some kind of automatic rm is dangerous and will
bite you sooner or later.

Bye, Tino.
