    Forgot to mention that I ran the "with" results before the
"without" results, so technically the files didn't exist yet and hence
the results are separate. But, just for absolute clarity for archiving
sake (and provided your suggestion on how to overlay both graphs),
here are the results:

$ for i in bw.*[0-9].log; do mv $i `echo $i | sed -e
's/\.log/_with\.log/g'`; done
$ python calc_runtime.py bw.*_with.log > _with
$ python calc_runtime.py bw.*_without.log > _without
$ ministat -w 72 _with _without
x _with
+ _without

Thanks for the tip :)!
