you need to use setsockopt() to set the SO_REUSEADDR option. that way the socket won't stay bound to a port after your program has terminated. Unix holds onto them by default just in case your program launches in the near future. there's a delay that you remove by setting SO_REUSEADDR. :)

int yes=1;
if (setsockopt(listenfd,SOL_SOCKET,SO_REUSEADDR,&yes,sizeof(int)) < 0) {
perror( "setsockopt" );
exit(1);
}
and I can start the server application right after stopping it without an error.
