Comment(by ddrake):
Another idea: use urllib2.urlopen
(http://docs.python.org/library/urllib2.html#urllib2.urlopen) which throws
an HTTPError when we don't find the list, and doesn't use any temporary
files at all.
{{{
try:
data = urllib2.urlopen(some_url)
except HTTPError:
# can explicitly check for a 404 if we want
print "couldn't find it"
sys.exit(whatever)
return data.read().splitlines()
}}}
