This patch introduces do_each_thread_reverse() and

because shell script makes a lot of short lived processes.
Reverse order search can detect it faster.
I like this change, thanks! I'm suprised we haven't needed a
do_each_thread_reverse() in the past somewhere else in the kernel.
Could you update the comment about do_each_thread() not being break-safe
in the second version, though?
ok.
