[Icecast] Buffer in IceCast

Hi Tom,

You might be right, but I don't get why my existing downloads (I guess they
are on different routes) are not affected. If my ADLS provider is doing some
IP adjustments (btw my IP is static) I expect everything to disconnect, not
only my icecast connection. So I'll monitor my USRobotics logs today and
tomorrow so see if there is something strange.

Regards,
