My Jinja2+Werkzeug's testsuite combined takes 2 seconds to run (Werkzeug
actually takes 3 because it pauses for two seconds in a cache expiration
test).  2to3 takes 45 seconds to run.  And those are small code bases
(15K lines combined).

It's not exactly two orders of magnitude so I will probably change the
writing to "just" 20 times slower but it illustrates the point.
