I took the original question’s statement to “Assume Highest Real-time
priority,” to limit the case to only highest realtime priority threads,
which of course will not timeslice. I believe that your statement is correct
and that Sajeev’s statement is incorrect with the inclusion of ‘equal’.

This is not correct. a Realtime priority thread will not be time sliced.
i.e. the scheduler will not do a time scheduling between two EQUAL real time
Priority thread.It will not switch back and forth between the threads of
equal Realtime priority. The Real time thread will only be pre-emptied if
HIGHER realtime priority thread is ready for execution.
Mark ,any comments??

Ofcourse a real-time priority thread will be
pre-empted if another RTP thread with equal or more
priority is ready to run. Incase of this being the
only RTP thread, it’ll continue to run as long as it
waits or completes. As Roddy mentioned, this need some
admin privileges
