I will, but my benchmark suite currently isn't usable outside my
development environment. I will try to make time to fix it up, and when
I have I will publish the code.

Which compiler are you using for this? I just tried you benchmark, after
some fiddling to make it build, and while my results match yours for
0.8.1, for 0.9 they are completely different:

This is with:

  gcc version 4.3.3 (Ubuntu 4.3.3-5ubuntu4)
