I already looked into that.  OpenBSD still doesn't have cross-process
posix semaphores, at least according to its man page.  NetBSD does,
but they consume an FD per sema, which is actually worse because
the default max-open-files-per-process is none too large either.

Yeah, I would not expend a lot of effort on this.  But two one-line
changes doesn't seem unreasonable.
