Re: v8 first impressions

Hi Dave,
Yes, I did. I emulated the "iterate for a second" loop from the V8
test and put it into a method. I then ran the test several times, with
only a marginal improvement (< 1ms). I took the same approach for all
of the Smalltalk tests, though it shouldn't make any difference to the
others since they don't implement adaptive optimization.

Regards, Steve
