I don't see how this could help because AFAIKS, child->saving is only

Sorry, that not right. There are some routines called by sched(), that
release
and reacquire the runqueue lock.
Oh yeah, it is the wake_sleeping_dependent / dependent_sleeper crap.
Sorry, you are right. And that's definitely a bug in sched.c, because
it breaks wait_task_inactive, as you've rightly observed.
Andrew, IMO this is another bug to hold 2.6.11 for.
