Subject: lockf missing.

Linux solution:

As lockf is not part of POSIX and Linux isn't true SYSV, lets just forget
about it and hope it will never happen that 2 people write in a message
database at the same time. Ugly!

Btw it has been reported that even SUN is still sending patches to it's
customers regarding lockf...

Alternatively i could go ahead and emulate lockf using fcntl, but than it still
won't be able to lock from a particular file offset.
