Yes, and very nice paper it is indeed, though I'm still curious as to
why all the dbench scores go down for SMP, even on the vanilla Linux

I guess that demonstrating the effects of the unification would have
to come under the scalability benchmarks section, and probably with a
non-IO bound test.  If Specweb doesn't support testing a bunch of
machines at once, perhaps you could fudge it by using IP Virtual
Server on another machine to distribute the load across the VM instances.
