The problem is that, when the frontend doesn't get any data while  
waiting for a stream to start, there are at least 2 places where it  
gets stuck in loops (tv_play.cpp:602 and RingBuffer.cpp:684) with no  
clean exit path.  I don't think it's in any state to accept a message  
from the backend either.  Trying to get it to at least accept the exit- 
playback keypress, I banged my head against this for a couple days,  
though somebody who understands the overall frontend architecture could  
probably do a better job.
