OK, this invokes a Windows question: how do I know that my VAX will

Is there a hook in Windows that will force the kernel and overhead
to only run on one specific processor while attaching the VAX
emulation task to a different processor?

Yes. This became a *very* important issue in the SMP versions of
CHARON-VAX -- processor context-switching was a big killer of
performance. The emulated VAX processors now grab hold of a host
processor and don't let go.
