Subject: epicsThread priority / a world beyond EPICS

I have an application with hard real-time demands
and I want to make sure it has a higher priority
than any of EPICS' threads.

Wouldn't it make sense to have a range of priorities
who are guaranteed to be unused by EPICS?
E.g. have
epicsThreadPriorityMax = 95
epicsThreadPriorityMaxMax = 99
and EPICS still checking that itself is never using
a priority > epicsThreadPriorityMax.

epicsThreadMaxMax would then be reserved for user
tasks.

Second question: if I create such a high priority
thread (currently not by using EPICS OSI but a generic
RTEMS call) - I guess it should be safe for that thread
to call EPICS primitives who are safe to call from IRQ context
(such as 'callbackRequest()'), right?
