AQMP likes to be very chatty about errors it encounters. In general,
this is good because it allows us to get good diagnostic information for
otherwise complex async failures.
For example, during a failed QMP connection attempt, we might see:

If we spy on the QMP commands instead, we don't need callers to remember
to pass it. Seems like a fair trade-off.
The one slightly weird bit is overloading this instance variable for
