No, that won't work - we don't want all posix opens to
fail just because a Windows client also has a file open,
we want the unlink to fail.

Exactly ! That's what I meant. A posix client does
an SMBunlink - we map that to ntcreate/setdelete on close/close
and we process the close differently (ie. deleting on first
close, not last) if all opens were POSIX. Clear now ?

:-). I have a source code control class to go to in 20
mins anyway.
