Anton Vorontsov 9bd0a07712 um: should hold tasklist_lock while traversing processes 
Traversing the tasks requires holding tasklist_lock, otherwise it is
unsafe.

p.s.  However, I'm not sure that calling os_kill_ptraced_process() in the
atomic context is correct.  It seem to work, but please take a closer
look.
