Oh, so you are the man behind bf!

Did you compile the sources with the Mono/MCS pair when comparing
against MS?  Currently MCS does not do two big groups of optimizations:
loop inversion in for loops (trivial) and it uses more opcodes than
necessary for tests/branches than it should (there is a bug report filed
against this).

Are the results the same when running the same compiled code (with CSC)
in Mono vs MS.NET?  Also, are the times taken at function entry/leave or
not?  Because there might be a penalty in Mono currently, as we lack
`ahead-of-time' compilation.
