I think I'll drop the diffs, you're right that current proven logic need
not to be changed for such rare corner case, which DBA can fix.

I've added references to ipcs(1) and ipcrm(1) in OpenBSD's semget(2) man
page, so newcomer won't need to spend hours digging in sysv semas
management, if one would encounter the same situation as I did.

Thanks for reviews.
