There's no way to set a timeout if you use "urllib" to open a URL.
"HTTP", which "urllib" uses, supports this, but the functionality
is lost at the "urllib" level.
It's not available via "class URLopener" or "FancyURLopener", either.
There is a non-thread-safe workaround from 2003 at
http://mail.python.org/pipermail/python-bugs-list/2003-September/020405.html
but it was rejected as a feature at
https://sourceforge.net/tracker/?func=detail&atid=105470&aid=803634&group_id=5470
without anything better going in. Despite this, current documentation
recommends that approach:
http://svn.python.org/projects/python/trunk/Doc/howto/urllib2.rst
Someone proposed to fix this
http://mail.python.org/pipermail/python-dev/2006-July/066967.html
but was discouraged from doing so.
The code was forked by Zope as a workaround in 2003:
http://pywebsvcs.sourceforge.net/apidocs/wstools/Utility.html
but that's not in the mainstream Python tree.
The correct fix would probably be to add methods to class
URLopener to control this; that's the usual way of handling special
URL opening situations.
