FWIW Ned, I had to update my (generally lame) résumé recently and was a bit embarrassed to put CPython on my list of projects that I've contributed to due to the same type of thing: it was a small patch that fixed an obscure issue.

Anyways, I did it anyhow (with the caveat to make me feel better :P) but I felt the same way about the "accomplishment" :). So congrats!

(This is tos9 by the way).
