Some performance results using speedtest -l, average of 5 runs with ignore=0

                Boehm version
                7.2     7.4.2
    asm_fast.gc 14.32s  14.04s
    hlc.gc      13.34s  13.30s
    hlc.par.gc  18.86s  19.04s

The variation is a little too high and the results too similar to draw any
concusions.  I'll test them again later with n=20 when I'm not using the
computer for anything else.  However it's safe to say that there's no
sagnificant performance regression.
