My plan is to work on instrumentation. This was just low-hanging fruit;
I was curious to see the impact on cache miss rates of bringing the TB's
close to the corresponding translated code. Turns out it's pretty small
or my L1's are too big :-) The memory savings are significant though,
with the added benefit that this can enable more efficient translated
code as Richard pointed out.
I've just left a message on the GSoC thread with ideas.
