  I know there is a way to surrender the rest of a timeslice in an MSDOS
session under OS/2.  I am unable to find out how this is done however.
I have some DOS programs the I run, but want to leave the CPU as free as
possible.  What I could like to do is this:

(global) int under_os2 = test_under_os2();

{
..
..
  while ( !kbhit() && !mouse_pressed() )
    if ( under_os2 ) surrender_timeslice();
}

  Okay, that's not the most efficent way, but you see that I mean.  It
drives me nuts to have a dos program that needs 3% of the CPU consuming
100% of it.
