Setting the SO_REUSEADDR option should prevent that, and in my
experience it always does.  What OS are you using?

Is there some reason you want to rebind each time?  Why not just loop
around the conn,addr = accept() .... con.close() section?

It is a known issue, but it's solved by setting the REUSEADDR option
on the socket before calling bind().  Are you sure you don't somehow
leave a server running on that port that prevents the bind() from
working?
