I wanted to use urllib2 with something as usual as binding to a given
network interface and it was incredibly complex. I also did not like the
usual propodes solution to timeout the connections: set the global
socket timeour. I needed a different timeout for each connection.

So I took my time, I learnt about httplib and urllib2 and made a patch
to enhance both libraries.

BindingHTTPConnectionWithTimeout extends HTTPConection with supports
timeouts and a binding address.

BindingHTTPHandlerWithTimeout extends HTTPHandler and basically uses the
new http class provided.

The patch is really simple and would make a great addition to the
standard library. I've tried to follow the style amd copied similar
methods, giving the due credits.

I hope you find it useful and consider it for inclusion.
