Incompatible with Python 2.4

[Bentis]

System:

• pyroutes 0.4.1 installed with easy_install
• mod_wsgi
• python 2.4

A request gives following trace:

Please submit bugs to pyroutes/pyroutes so klette doesn't have to report the bugs to me by IRC :p

Don't have python2.4 on hand, may be other changes required for python2.4 -- Absolutely sure the test suite breaks there.
