After I do my i386 OS / AMD64 hardware benchmarking tests, I'll post
the results here and then a summary of all of this to freebsd-threads as it
does seem to be becoming more of an issue for them than the AMD64

I guess we'll know that from the upcoming i386 benchmarks, how libpthreads
is working for MySQL on either port.
