so, we played a little game with Stefan: i wrote a simple stack-based VM implementation for our beloved bug6498, and got 270 msecs with debug build, 140 msecs with release build. can be made even faster with some simple peephole optimizer (it has two hacks to get fair times on 6498, but this is not a good peephole opt ;-). of course, it scales linearly too.


don't expect me to join the race, though: i was just curious how well stack-based VM can do.
