The reset code is much older than the safe-async support for
running things in the vCPU context... Also, does the safe
async support work with KVM/HAX/Hypervisor.Framework? The
reset code has to handle all those, not just TCG.

Plus, which vCPU thread would you use? We're resetting
the entire system, so privileging an arbitrary vCPU
thread to do that doesn't seem any less odd than using
the main loop thread.
