The usual case this happens is you have a client connection open at the 
time, that was not properly terminated. Then the TCP stack goes through a 
holdoff period (2 minutes, I believe it is), to make absolutely sure all 
packets destined for the old connection have completely disappeared off the 
entire Internet, before it will let you open a socket on the same port
