Subject Re: Introduction, and a question

I brought up this idea with Lars Bak (HotSpot architect at Sun back 
then) at a conference some years back when Sun introduced the HotSpot 
VM. The argument back then was that a program mays not execute in the 
same pattern every time and the optimization made previously may no 
longer apply.
