I have had some strange results with VMS idle detection as well. 
Sometimes I can boot the emulator and it consumes 100% of a cpu.  I shut
it down and immediately reboot without changing anything and the idle
detection works fine.  I think it got better when I raised one of the
parameters.  I can post my vax.ini when I get home from work.
