While I have no doubt that it shows me something, I had no idea what
that might be until I tracked down prime.rb in the source - if this is
supposed to be readable without access to the code being tested, I
don't understand.  (And if it isn't supposed to be readable without
looking at the test source, why is it so hard to find that source
file?  I shouldn't have to download the distribution to be able to
read the documentation.)

Now that I've seen the source, and gone over what it says in
graph.txt, I have a slightly better idea.  This might indeed be able
to tell me something; I'll have to try it thw next time I'm trying to
optimize ruby.

It'd still be nice to have something like perl's Devel::SmallProf, but
I think I can live without that for a bit.
