Agreed.
But in the name of science (science!) I've run the a/b test that Tom
suggested (with the abababaaabbb pattern, even), and these were the results:
Trunk Patches
Run #1 443.093 448.851
Run #2 440.845 445.338
Run #3 439.795 445.746
Run #4 437.751 462.278
Run #5 439.482 460.737
Run #6 436.606 461.509
Mean 439.595 454.077
Std Dev 2.288 8.245
(I won't speak as to whether all of these decimal places are warranted, but
unittest reports milliseconds, so I'm sticking with three places all around)
All times are in seconds. This was tested on Python 2.6.7, and SQLite,
against Django trunk from this morning (a), and Vinay's 3k-compatible
branch from yesterday (b).
