Just did as you asked and things seem fine. Ran on an SGI altix.
(The first process shown below shouldn't have a priority of 99,
just the others.)

cranberry5:~ # ps -eo pid,rtprio,comm | grep xpc
13325      - xpc_hb
13327     99 xpc08
13467     99 xpc06
13469     99 xpc06c1
13501     99 xpc06c1
13502     99 xpc06c1
