Summary: asyncore.dispatcher.set_reuse_addr() is broken on windows

Initial Comment:
asyncore.dispatcher.set_reuse_addr()  uses
socket.SO_REUSEADDR to allow reuse of same address
without having to wait. 

On windows this also allows multiple programs to bind
to the same socket adress. What is probably needed is
to use  SO_EXCLUSIVEADDRUSE on windows which has the
same meaning as SO_REUSEADDR on all other platforms. 

This will stop people running the server multiple times
and getting wierd results or two programs sharing the
same port without realising.
