So, assuming your app is single-threaded, set the timeout, call
urlopen(), and reset the timeout to None.

That's not so easy even if you were to have a timeout parameter to
urlopen(). You'd have to implement that peculiarity in all the layers
(in this case, urllib and httplib; and possibly ftplib, gopherlib etc.
