While this would work, I don't really see the need for it given the
availability of nonblocking operations.  See mq_putmessage() for an

Makes sense, and I'm not especially concerned. If the expected solution to such usage is to use non-blocking calls, that's fine with me.

I partly wanted to put this out there to help the next person looking into it. Or myself, when I've forgotten and go looking again ;) . But also, to ensure that this was in fact fully expected behaviour not an oversight re applying shm_mq to non-bgworker endpoints.
