Well, the problem here is that when the simulated CPU does nothing the
simulator is still running 100%. That means simh has to be patched to
"idle" on the host system as soon as the simulated CPU is "idle". You
can't solve the problem from Windows, as far as I know.

But if someone knows something I don't, do tell!
