[Icecast] Problem with fallback on 2.31 on Windows XP

[Steve Matzura]

Everything's now up and running correctly, with one unrelated problem:
When I disconnect the live stream and it goes to the fallback mount
point, sometimes it's very slow to fall back, and sometimes I get the
famous problem that acts like a speed mismatch, where the fallback
stream plays slower or faster, or buffers so badly that the listen
port has to reconnect in order to sort it out. Both encoders--the live
and the backup--are running at the same bit rate. Any other things to
check?
