  Yes, but they don't help much... I have them at minimum for most DOS
  sessions, but there are some comm programs which miss bytes when you
  set their IDLE_SENSITIVITY too low, and hog the CPU otherwise :(((

  There is one other thing I noticed: when a DOS program hogs the CPU,
  even though the CPU meter shows 100% CPU usage, most of the OS/2 apps
  start and run OK and they slow down just a little, but other DOS
  sessions almost grind to a halt! Do you see that on your machine?

  This is not such an issue any more, since I almost totally migrated to
  native OS/2 programs, except for some rare DOS apps like this QWK
  reader I'm using right now... and it multitasks under OS/2 better than
  even some native OS/2 programs! It detects which multitasker it's
  being run under (detects a whole bunch of them, including OS/2,
  win3.1, win95, winNT, Desqview, Topview etc) and releases cycles
  accordingly. It uses the undocumented DOS INT 28 when run under OS/2.
