Yea, it worked by keeping state for each block and re-using that to speed
up skip-blocks, follow-jumps, etc etc if I recall.

It made huge improvements for speed, but I don't recall having any data on
its memory consumption.

I believe I've still got a copy if someone wants to start poking at it;
though I suspect Mark would rather us spend time dealing with issues
directly related to GCC 3.0.
