I've came across to the need of a flock(1) utility at work and I've
noticed we don't have any in OpenBSD, it's basically a flock(2)
wrapper that is usefull for running shell commands under a exclusive
and/or shared locks.
From a compatibility standpoint you should consider just bringing across
the lockf(1) command from FreeBSD:

It's also a hell of a lot simpler than the Linux one.

Debugging? Klingons do not debug. Our software does not coddle the
weak.
