[icecast-dev] PATCH: increase network congestion resilience

Hi,
        find a patch which is an update to a patch sent months ago. Before it was 
in net/sock.c, now I moved it to format.c, so net CVS module is not 
affected. It polls the socket before trying to send() any byte to check 
if the TCP buffers are full due to network congestion.

See below the warning messages of "normal" (at least in Spain :-) 
temporary congestions in the network. The server could keep the 
connection without any problem. You can try it also by unplugging the 
ethernet for a couple of seconds.
