For this particular problem, the principles are more important that the exact results, but I'm happier with tbray7.cpp which gives the same results as the regex in the original ruby code:

fortinbras:$ time bin/tbray7 datasets/hundred-o10k.ap 
matches: 95400

real    0m0.439s
user    0m0.284s
sys     0m0.144s

The file was in cache for that one so ignore the real time; the important thing is that the user time wasn't adversely effected by getting the 'right' answer, instead of 1100 matches.
