A bit more research later: OpenBSD behaves like NetBSD, while
FreeBSD behaves like Linux.  So that's pretty inconclusive about
what the aboriginal behavior was.  I also found that OpenIndiana
behaves like Linux.

For Linux and FreeBSD, it doesn't actually matter to us because
we no longer use SysV semaphores on those platforms.  But this
is a live problem on macOS, NetBSD, OpenBSD.
