Does this really work as expected? From a quick glance I get
the impression that the exit handler is called in the child.
The queue however is only maintained in the parent. The
effect would be that even a fully busy child will exit after
the event triggered, in the child it does not see whether
the parent still has work for it.

Have you tried if a busy child does *not* exit?
