No, no.  What I meant is, in POSIX systems you can unlink() stuff
which is currently opened by the same or another process.  In
Windows you get a permission denied or something.  Cygwin has
actually a workaround which is to maintain a queue of stuff which
should be unlinked but couldn't due to open descriptors.  Therefore
the removing returns success since the unlink hasn't been done yet
but it's queued and will be performed when possible.  The following
mkdir fails since the directory still exists.  That's rather
difficult to do as a POSIX system expects with the underlying
Windows behaviour.
