Sky asked me if anyone had done any simple benchmarks comparing JVM
and PVM at this point. Now, I know we're still at an early stage and
haven't really looked at speed, but a trivial counting and simple
arithmetic benchmark:
piglet$ time java Bench
1.470u 0.080s 0:01.59 97.4% 0+0k 0+0io 5784pf+0w
piglet$ time ./test_prog run.pbc
40.080u 0.030s 0:42.07 95.3% 0+0k 0+0io 137pf+0w
Source files attached so I can humiliate myself in public at a later
stage when someone points out I've done something stupid

ps my jvm is j2sdk-1.3.1-FCS from blackdown on linux
ps2 oh, and are we calling it pvm? parrotvm?
