— Change the definition of thread priorities
The old definition was quite unpredictable and too platform-specific.
The new one defines -1.0 as lowest priority that still schedules, 0.0 as
the normal priority (meaning the same as the main thread) and +1.0 as
the highest priority that still allows getting preempted. (user: js, size: 3956) [annotate] [blame] [check-ins using]
