Comment:

 In the longer term, we should submit patches upstream. urllib and urllib2
 (and other modules) compile a bunch of regular expressions at import time
 but aren't always used. This is very expensive in terms of memory usage
 and cpu time.

 I have seen other modules in the python standard library where regular
 expressions have been obviously moved to be compiled lazily, so I think
 our patches will be accepted without much problems.
