SCO Xenix (i only looked at 2.2.1 for the 286) has a system call "plock"
which does this (when executed by root).

System V release 3.2 claims to be compatible with Xenix but fails in this
area as it does not have the plock call.

I'm afraid you are out of luck at this time, at least when looking at
the 'standard' unix versions. (BSD and SYSV).

Paul.
