Any way to fix that "4 times as many page misses, and 70% bigger rss?" 
thing? It looks like you're not very careful about your memory use.

I realize that git in general wants a lot of memory, but I see that as a 
failure most of the time. I've got 2GB in most of my machines, but I 
shouldn't _need_ to have it..
