sched_setparam() clarification

[Mark Brown <yyyyy@xxxxxxxxxx>]

There is a questionable element of sched_setparam() for which 
we want clarification that the behavior as written is truly what 
is intended by the standard.

XSH p.1232, lines 38394-38395

     "The target process, whether it is running or not running, 
      shall be moved to the tail of the thread list for its priority."

This has the effect of forcing a running process to yield if its 
priority is set to its current priority.  It seems peculiar to force
a running process to yield the CPU if its priority has not been made 
less favorable.  Is this actually as intended?
