Tests on FreeBSD (celeron 2GHz-or-something instead of Athlon64 4800+):

% for n in res*/*/stats.csv; do echo $n; cat $n; done
results/cvsimp-mtn030-time/stats.csv
cvs_import-system-time,0.41,0.44,0.4
cvs_import-user-time,51.56,50.35,51.99
cvs_import-wall-time,58.46,57.42,75.21
results/cvsimp-mtn061008-time/stats.csv
cvs_import-system-time,0.33,0.29,0.36
cvs_import-user-time,174.44,185.09,191.5
cvs_import-wall-time,193.42,224.3,247.97

so.. except that Cygwin has quite an speed hit on monotone (not a news)
the speed problem of latest trunk mtn is only worsened on FreeBSD!

I wonder if it is the same on Linux... we should have a couple sticking
around at the office, tomorrow I'll try some more tests maybe ;-)
