[Live-devel] Event loop and threads

What may be happening is that your event loop has no pending events 
(i.e., no incoming network packets to be handled, and no pending 
delayed tasks).  If that happens, the event loop will (quite 
correctly) block indefinitely in "select()", and will never get 
around to checking the watch variable.

For a way to overcome this, see

Right now "lists.live555.com" and "ns.live555.com" are the same host. 
That might not remain true in the future, though.
