[PATCH] Call exit_itimers from do_exit, not __exit_signal 
  
 When I originally moved exit_itimers into __exit_signal, that was the only 
 place where we could reliably know it was the last thread in the group 
 dying, without races.  Since then we've gotten the signal_struct.live 
 counter, and do_exit can reliably do group-wide cleanup work. 
  
 This patch moves the call to do_exit, where it's made without locks.  This 
 avoids the deadlock issues that the old __exit_signal code's comment talks 
 about, and the one that Oleg found recently with process CPU timers. 
  
 [ This replaces e03d13e985d48ac4885382c9e3b1510c78bd047f, which is why 
   it was just reverted. ]
