yep, agreed, this is another bug. It is fixed by an existing scheduler
patch (queued for 2.6.2, sched-cleanup-2.6.0-A2) but we might want to do
it in 2.6.1. I've attached the patch, merged relative to 2.6.1-rc3 +
your version of the threading fix. The changelog:

- separate out the scheduler-state initializations from the fork path
  and push them into sched.c.

- this also fixes a bug: CLONE_STOPPED tasks were not fully set up.

yep, agreed, your patch is cleaner. (i've test-booted it on SMP, it
works fine. I've also test-booted the sched-cleanup patch.)
