NEPOTISM_BONUS yield_to_child() ?

[Robert Redelmeier]

  		[YAFR - Yet Another Feature Request]

Multi-threaded/tasking performance is entirely 
dependent on the OS scheduler.  I searched
	/usr/src/linux/Documentation/scheduler/*
and found no mention of parent or child processes.

Parent- and child-processes are interconnected, and for maximum [SMP] 
performance, these connections should be recognized _optimally._

For example, on some [desktop] systems, an exec() syscall would run
unblocked, an exit() would return the rest of the timeslice to the
parent, yield() would go to child (parent?), etc.  Other servers
might choose the exact opposite.

This connectivity could be implemented by a tuneable scheduler param:

  NEPOTISM_BONUS = int

where positive values would influence the scheduler to run
parents/children/uncles/nieces and negative values would
cause the scheduler to prefer strangers [unrelated procs].
