I will add the following to epicsThread.h

static const unsigned epicsThreadPriorityIocsh = 91;
static const unsigned epicsThreadPriorityBaseMax = 91;

Any objections?

and I think Till would agree, that the IOC shell should also run at a priority less than the scan tasks to ensure the determinism of the scan tasks.

Booting tornado II gives

Thus to ensure really good real time performance the priority of all of the above should be changed.
