[Python-Dev] PyDict_SetItem hook

[John Ehresman]

Just want to reply quickly because I'm traveling -- I appreciate the 
feedback from Raymond and others.  Part of the reason I created an issue 
with a proof of concept patch is to get this kind of feedback.  I also 
agree that this shouldn't go in if it slows things down noticeably.

I will do some benchmarking and look at the dtrace patches next week to 
see if there is some sort of more systematic way of adding these types 
of hooks.
