Benchmarking: FreeBSD MD5 [32/32]... DONE
Raw:    4283 c/s real, 4283 c/s virtual

Benchmarking: FreeBSD MD5 [128/128 SSE2 intrinsics 12x]... DONE
Raw:    6540 c/s real, 6540 c/s virtual

Where's the regression?  I see algorithm change and a speedup here.
(Low speed either way, but that's expected for that machine.)

Benchmarking: MediaWiki -- md5($s.'-'.md5($p)) [SSE2 32x4]... DONE
Many salts:     3708K c/s real, 3708K c/s virtual
Only one salt:  1361K c/s real, 1361K c/s virtual

Benchmarking: MediaWiki md5($s.'-'.md5($p)) [128/128 SSE2 intrinsics 10x4x3]... DONE
Many salts:     2266K c/s real, 2266K c/s virtual
Only one salt:  1377K c/s real, 1377K c/s virtual

Also an algorithm change, and one that resulted in a slowdown this time.
Need to test these on more/newer machines, I guess (including also 32-bit).
