[Simh] TOPS-20 V4.1 Idling

[Cory Smelosky]

Okay, I should include all the information needed now. ;)

With CPU IDLE set, with CPU set to TOPS-20 (running 4.1 running the TSU02 
monitor) SIMH continues to use 100% CPU.

Does anyone have pre-existing patches to support idling or do I need to 
provide a disk image to help identify it?

Alternatively...some people here probably already know the idle 
instruction. ;)

PDP-10 simulator V4.0-0 Beta        git commit id: 3b8c318b

( Interestingly, SET THROTTLE 20 causes >30% CPU usage, whilst 15 is 5% 
which is just slightly above it being set to 12.  This doesn't seem 
linear. ;) )
