Try adding:
to /Library/Python/2.5/site-packages/Paste-1.7.1-py2.5.egg/paste/httpserver.py, line 360, immediately after this line:
This sets the REUSEADDR flag on the socket, which allows it to keep the original port it started out with.
self.socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)to /Library/Python/2.5/site-packages/Paste-1.7.1-py2.5.egg/paste/httpserver.py, line 360, immediately after this line:
self.socket = socket.socket(self.address_family,
self.socket_type)This sets the REUSEADDR flag on the socket, which allows it to keep the original port it started out with.
Force all sockets to use the REUSEADDR flag

....alternatively, you could go into /System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/SocketServer.py, line 323:
and set it to True instead.
This will then affect line 341:
and force the application of the SO_REUSEADDR flag to any socket. This changes the fundamental way socket servers behave in Python, so it's kind of heavy-handed.
allow_reuse_address = Falseand set it to True instead.
This will then affect line 341:
if self.allow_reuse_address:
self.socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)and force the application of the SO_REUSEADDR flag to any socket. This changes the fundamental way socket servers behave in Python, so it's kind of heavy-handed.
