This is a complete scheduler policy rewrite designed to be intrinsically 
interactive yet very simple and scalable. See previous announcements for 
more details.

This version addresses a few minor bugs that are somewhat difficult to 
stumble upon but can cause problems. Thanks to the many people who 
reported their experiences so far, and especially to Pauli Virtanen for 
extensive testing of a nasty bug and feedback along the way.

This version improves the gameplay on some games that seem to depend on 
yield() for locking in places (eg Unreal Tournament), as well as 
removing an "exploit".

Changes since 7.0:
7.1:	Yield() wasn't putting yielded tasks last, yield logic improved.

7.2:	Internal

7.3:	Yielded tasks were gaining burst by yielding, this was removed
	as it was inappropriately rewarding tasks that yielded.
	Forked tasks were gaining burst by forking. This was removed as
	for yield()
