 Problem ? It's a fact and always will be that multi-tasking
operating systems and real time processing don't go together unless the
real time demands are very long relative to the processing speed (eg.
payroll).

 Time was we used MS-DOS for burning CDs rather than unix because
it only took one late write to make a coaster, buffering and faster
processors means that we can now burn blu-ray discs from a multi-tasking OS
and almost never make a coaster. That doesn't make unix a real time OS it
just means that the timescales have shrunk.
