Hmm, a more careful 2nd reading may have answered my question, but I'll ask 
anyway--on first reading I wondered if that was true of any program running in 
/ making use of a Linux realtime kernel--that is, that the realtime program 
(linuxcnc) (or is that the kernel) has total control over the  machine.

On 2nd reading, I think the answer is yes, i.e., if I have a midi program 
making use of the / a real time kernel, it will have total control of the 
machine and other programs will have the "leftovers"?
