Mutilate brings us back where core scheduling does bad on baremetal,
but fine in VMs. The benchmark seems to be much more sensitive to
HyperThreading when run inside virtual machines, and core scheduling
guarantees better results than disabling hyperthreading, in such cases.
Interestingly, this time the thing is more evedint in the *non*
overcommitted scenario.

In fact, with one 8 vCPUs VM, v-VM-noHT is -87.35% and VM-csc_vruntime-
HT is only -1.06%, which is really good. In the overcommitted case, v-
VMx2-noHT reaches -97.21% while VMx2-csc_vruntime-HT is -83.92%. So,
yeah, better, but not "as better" as before.
