Yeah, this code was written for a MUCH older version of Pyrex.

Three argument form won't help here, as the AttributeError case falls 
through to more complex calculation.

Offhand, it seems like the right thing to do here, since the raise 
doesn't need to have high performance, they could just raise 
*sys.exc_info().  (So to speak.)
