Forgot to mention... Also, it doesn't try to fix the race with do_exit(), this needs another change.
And, damn, can't resist. This is mostly cosmetic issue, but I feel discomfort every time I look at task_oncpu_function_call(). It _looks_ obviously wrong, even if the problem doesn't exist in practice. I'll send the pedantic fix to keep the maintainers busy ;)
