I suppose, what I need to do is

a: Benchmark both guys on the hardware.

b: Probably introduce either a Bitmap like scheduler, or gaurantee that 
only one process will _ever_ be running at a given priority.

c: Find out if when an ISR releases a process from a wait queue, if that 
immediately runs the scheduler, or if it simply releases the process to 
be run on the next scheduler iteration.

I'd also be curious, of the timeslicing schedulers which come with 
two-six, which ones are in use and why.
