[Simh] doorbell

[Villy Madsen]

I don't disagree, but I fear that such a task would be beyond my resources. 
  What I am hoping for is a method of getting performance data from VMS 
down to the simulator agent - perhap via an unused device CSR - like the 
DN-11.

Trying to throttle using instruction patterns sounds a little too 
complicated - at least to begin with
