The Monitor needs lots of cleanups to make things more obvious.

Only the commit log 940cc30.
Basically, an asynchronous handler has a completion function which is
called when the handler completes.
If we're in the user Monitor, it's suspended until the completion
function is called. In QMP, the handler returns immediately and we
_should_ be emitting an event when we have the answer.
The current code doesn't do that, which seems to be a new issue.
