Wolfgang Bumiller 2895aaa139 monitor/qmp: resume monitor when clearing its queue ... When a monitor's queue is filled up in handle_qmp_command() it gets suspended. It's the dispatcher bh's job currently to resume the monitor, which it does after processing an event from the queue. However, it is possible for a CHR_EVENT_CLOSED event to be processed before before the bh is scheduled, which will clear the queue without resuming the monitor, thereby preventing the dispatcher from reaching the resume() call. Any new connections to the qmp socket will be accept()ed and show the greeting, but will not respond to any messages sent afterwards (as they will not be read from the still-suspended socket). Fix this by resuming the monitor when clearing a queue which was filled up.
