Yes, a friendly cohabitant of this lab just told me to rtfm and also
consider it; I do agree, I think currently this would stop stop() from
stopping().

Yeah, but why don't we just poke that variable on stop()? Ignoring the
work calls that might under non-stop() circumstances might occur from
message queue handling would imho be perfectly fine when stop() has been
called.
