This is even better than kernbench! :-)

Basically, both on baremetal and in VMs, noHT causes some -81.29%. With
core scheduling, the worst we get is -6.40%.

And that's in the not Virt-overcommitted case. In such case, noHT
brings us down to -248.65% (i.e., we are ~250% slower, it's not that
we're going back in time :-P). Core scheduling contains the damage to
either -72.76% (Tim's patches) or -92.64% (vruntime). While plain v3
is, again, worse than both.

Overhead looks similar to other cases already discussed.
