Solution for: #4: Paster restart socket error

Force all sockets to use the REUSEADDR flag

....alternatively, you could go into /System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/, line 323:

allow_reuse_address = False

and 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.
