Well, pre-emptive would mean that the code execution and transition to
next code routine would be controlled by some superior process, as
opposed to being cooperative and controlled by each routine.  This
would allow each routine to be alloted some amount of execution time. 
(pre-emptive=linux multitasking cooperative=windows 3.1 MT) Likely on
a PIC it would not be of much value because the p16 only has 8 levels
of stack.  I am not trying to do anything except perhaps suggest that
it would be possible to do this on a p16 if anyone needed to use it
for something or other.  Just got bored =P
