>Description:
icecast uses 80% of the CPU without any encoders or clients
connected. The problem is that it spins while waiting for incoming
connections. The timout there is only 30 microseconds for select.
Increasing this value to 30 seconds solves the problem with no
adverse effects, bar the mt->ping not being set as often. But that
should not be too big a problem. Other threads also set timeouts/sleeps
for more then 5 seconds.
