## The code below demonstrates the problem

## #!/usr/bin/env python 
## import asyncore
## import socket

## class EchoServer(asyncore.dispatcher):

##         asyncore.dispatcher.__init__(self)

##         self.set_reuse_addr()
##         self.bind((host, port))
##         self.listen(5)
##     def handle_accept(self):
##         pass

## server = EchoServer('localhost', 8080)

## Without the patch, this never breaks out of the loop.
