[HECnet] KLH10 not idling host CPU

[Mark Abene]

As I said, cpu idling is enabled by default in the supplied klt20.ini, and
it always used to work. When it stopped working I can't say, but seems to
have been in the past couple of years. I suspect something had to have
changed in the use of the interval timer. But it's definitely a problem.
