[mythtv] [BUG?] Endless waiting for thread...

 All the socket based plugins in mfd work this way. There's also a pipe that's 
watched, so in a single select() you can wait for anything coming in on the 
socket, anything going out to any clients, or a signal from any other thread 
that the select()'ing thread should wake up (ie. any other thread can just 
put a few bytes in the pipe, and the select() will return). Works well.
