That was me. That was a 33% speedup on win2k startup time. kqemu (user
only) has a negligible impact on win2k startup time which suggests this
is mostly ring 0 code running which would make it a good benchmark for
kernel-kqemu performance.
This was a terribly unscientific benchmarking so don't read too much
into it.
