You're quite correct.  I basically never use -O, mostly because 
I never think of it (nor care about performance enough).  A quick
test shows that with Python 2.2 and -O, I can get roughly half
the speedup that I get going to Python 2.3.  I'll investigate
more thoroughly on a work machine next week.
