I have asked this before on this thread, but didn't see any answers,
so I will ask again: doesn't RHIDE hook the timer inetrrupt?  If it
does, and if it doesn't unhook it when running child programs, then
this might explain the behavior on DOS (an extra level of interrupt
handling).  And Windows might change its scheduling of a program that
has hooked the timer.
