[Simh] No recognizable idle loop

[Brian Knittel]

Their idle detection scheme works within VMS,
and I'd be willing to bet that their "idle.exe"
utility communicates directly with the emulator
via some sort of special trap instruction.
In a sense, they're modifying the operating system 
and letting it know that it's running on an emulator.

When you break the fourth wall, so to speak, just 
about anything is possible.
