Yes, it's a case of normal running is fine, but on some network error
one or more threads go into busy loop not emptying it's queue.

That can happen, usually there is some fluctuation and depending on
the tollerance that can stuff the just one or even all the streams.  A
lower bandwidth stream won't sent as much data for instance.

Well assuming a pure clock change, a change of 10 secs could cause an
extended sleep period in which icecast could drop the connection. In
this case increasing the source-timeout is not the right solution as
a 10 second gap in audio streaming is really bad! 
A simple log message could help track those type of problems. If the
sleep is over say 2 seconds then show warning. hmmm patch brewing!!.

The send_raw one fixes the busy loop problem, and the ices patch
prevents excessive memory usage and few seg vaults that had shown up.
