Queued, thanks!  Synchronization of special registers is the obvious
next step (hint, hint!).

Cameron perhaps can also guide us with respect to the CPU kick race that
I mentioned in my review of patch 4.  A full fix is not possible without
help from Hypervisor.framework, but using hv_vcpu_run_until will already
tighten the window for the race.

Thanks,
