By the way, I would be happy to work with someone on analyzing this
stuff. I've just put in another round of development on Meliae while
trying to sort out some bzr issues. It would be nice to work with
someone to get feedback about what does/doesn't work for them, and ways
to improve the memory analysis.

Also, one thing to consider. If you are worried about memory *leaks* it
is probably best to get 2 dumps over time. There may be a lot of noise,
but having a delta of how the memory grew can be useful.
