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.
