What was actually fixed? Python is an interpreted language, and until 2.5, only 
grew in its memory usage (no free'ing of GC'd memory). Let me know if we should 
close this out...

Go ahead and close it.
Without the fix, python would get stuck in an infinite loop where it would 
repeatedly append self.SRE(self.data) to l, and this would cause python's mem 
use to grow to fill all available memory, both physical and swap.
Memory leak was not the proper term.
