I did.  "for x in xrange(10000000): pass" (cut and pasted, Python 2.2, 10 
million passes) takes about 1.5 second (estimated by 'one thousand and 
one...' method).  Divide by 10000 for your 1000 iteration test.

Valid comparitive data from honest and competant testers with different but 
properly functioning systems.
