or perhaps create a sysop command for the message menu that creates the semaphore for triggering (so in this case "forcing") a message poll.

I already have full controls to force those things in the Message Menu.
Anyone can force them if they think it will help (if it's not working it
will help). I'm letting it play out with the current A47 (6/7) to see if
it will stay working.
