I've been having trouble tracking down what causing this. A some point, after an hour or two or so, I start getting lag between keystrokes. Since it takes so long to happen, isolating the problem is taking forever. I have no per-key-stroke events or functions that I can find.
This was a sure prelude to Vim70c crashing. Vim70d seems to be crashing less, but the lag still creeps in. I can't really be sure if it is strictly a Vim 7 problem, since the scripts I'm working on all are using Vim 7 features, so testing with Vim6 isn't an option.
