Right... but for a *nix system to map calls to say lockf() to SMB/CIFS calls,
it's just not possible because the lock semantics are different.  If for
example, you want an exclusive record lock in *nix, you MUST open with write
intent plus some other semantic weirdness... what I'm suggesting is that
although SMB/CIFS supports specific file/record locking, *nix itself does not,
so you'd either need to use some platform-specific SMB/CIFS library in the
program or handle the SMB/CIFS stuff yourself to get correct bahaviour.

Possibly the call deadlock response is caused by the fact that our lock()
implementation uses both flock() and fcntl() locks.  Not sure, I'd have to
experiment (after the holidays unfortunately)
