If you want to release the time slice, write your own sleep function.

Maybe something like this:

void sleep(int msec)
{
  clock(); //Can't remember which fxn to use
  do
    _dpmi_yield();
  while(!(clock()>=msec));
}

I'm not sure that I wrote this right, but it should work.

Perhaps because DJGPP is DOS and DOS is not multitasking sleep just
wastes time rather than giving the time back to the OS to be used by
other processes.

No this is not NT being silly because sleep works as expected when
compiled with VC  and Borland 5.0
