Compiling with gcc and -g, with no optimization, 2.0 and 2.1cvs seem
to be very close, with 2.1 slightly slower:

2.0:
Pystone(1.1) time for 10000 passes = 1.04
This machine benchmarks at 9615.38 pystones/second
This machine benchmarks at 9345.79 pystones/second
This machine benchmarks at 9433.96 pystones/second
This machine benchmarks at 9433.96 pystones/second
This machine benchmarks at 9523.81 pystones/second

2.1cvs:
Pystone(1.1) time for 10000 passes = 1.09
This machine benchmarks at 9174.31 pystones/second
This machine benchmarks at 9090.91 pystones/second
This machine benchmarks at 9259.26 pystones/second
This machine benchmarks at 9174.31 pystones/second
This machine benchmarks at 9090.91 pystones/second

Would it be worth experimenting with platform-specific compiler
options to try to squeeze out the last bit of performance (can wait
for the betas, probably).
