When I first read this, I thought you were crazy. I ran the
code, and you're not. I tried under versions 2.3, 2.4, and 2.5
on my Debian box, and got the same results. Neither "cathy" nor
"ca" works, but "c", "cat", "cath", "cath_y" and "cathy_" all
work just fine.
Even more infuriating is that if I try and use pdb to debug,
Swaroop drops into pdb, but Abdul and Cathy both error out.
That's just plain nuts. Something odd is happening with __del__
