Thanks, Karl. Testing with trunk I can confirm this. Just as before it
doesn't seem to make difference if icecast streams something or not,
but there is a significant improvement compared to 2.3.2:

2.3.2     44 wakeups/s
trunk     13 wakeups/s

13 wakeups is still not optimal when in reality my icecast usually has
nothing to do (no mounts, no clients), but it is a lot better.

Thanks for the good work,
