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. > But TBH, nobody uses openbsd and netbsd if performance matters even one > iota.

But two one-line changes doesn't seem unreasonable. regards, tom lane
