IOW, my slow thread has to have its addf list between "process" and "write outputs" So, I guess the best way to test this is to raise the slow-threads rate to match the servo-thread and see if that causes timeing overruns out the wazoo. Or set it down to really slow and see if it still works. What we need is not "hard real time" out of threads, but a way to set the priority of the threads it creates, and we do not now have that. Is it too late for a feature request for "soft threads" to get into 2.8 final? This jog-wheel stuff can I'm sure, be run on leftover time as long as there is some "leftover" time. Thanks Peter.
