Can someone post test cases or benchmarks for call/cc? I'm cranking up
my Ruby profiling test bed this month and should have everything
functioning in the next day or so. So far I have only BFTS, the tests
and benchmarks in the Ruby 1.9 SVN repository and my own Matrix benchmark.

Some details: Gentoo Linux, 2.6.22 kernel, gcc 4.1.2 (4.2.0 breaks a lot
of other stuff -- it seems to be fine on Ruby), Athlon64 X2. I've also
got the AMD CodeAnalyst tool set but I don't know if it's functioning yet.
