Given the current interpretation of Ada priorities and
preemptive scheduling, it seems that compiler vendors that supported
priority levels but not preemptive scheduling now have
two choices...

1. Modify their runtime to support preemptive scheduling.

  	This may be expensive or impossible if the underlying hardware
	does not have time driven interrupts.

2. Restrict priorities to be a single number (i.e. disable pragma
   priority)

My question is... are we losing something here?   Is there
a value to having multiple priorities even if we don't 
have preemptive scheduling?
