By the way, why semid argument of this semctl() is so high? Perhaps it would
be worth ktrace to be sure what is exactly passed. Also, what ipcs(1) shows?

A while ago (well, 10 months ago), this validation check was added, see rev
1.83 of sysv_sem.c source. From the quick glance, it looks OK to me, however.
