The qemuAgentIO and qemuMonitorIO callbacks also add have matching
Ref/Unref calls along side the lock calls, but after scratching my head
over it for a while I don't think it's necessary here: even if
virConsoleShutdown is called from one of the callbacks, the main thread
will still hold a reference until the callback releases the object lock
