Sorry I can make a more detailed post right now. I'll make time in the next couple of weeks to post some code and timings that document the collision counts, total memory size, and its affect on various dict use cases.

Is there some way to instrument dictionary sparseness, number of hits and misses, etc. from Python?

A secret command-line switch, perhaps, or a compile-time option?

And if there isn't, perhaps there should be.
