MS-DOS is not designed to know that other programs may also be running at the 
same time. What are you trying to achieve by 'waiting'?

Anyhow, if you really must, I recommend trapping INT 1C, and when you 
want to 'wait', just count the appropriate number of ticks (65535 per hour)
and when not waiting, just ignore the interrupts.
