This could be.

But looking at cmdctl.py in particular I see:

class SecureHTTPServer(socketserver_mixin.NoPollMixIn,
                       socketserver.ThreadingMixIn,
                       http.server.HTTPServer):
    '''Make the server address can be reused.'''
    allow_reuse_address = True

This should allow reuse, as http.server.HTTPServer is a subclass of
TCPServer, which has that variable for just this purpose:

http://docs.python.org/py3k/library/socketserver.html#socketserver.BaseServer.allow_reuse_address

To be honest, looking at the systest errors I can't really tell what is
going on. :( Hopefully Lettuce will be a bit more clear.
