Boeing philosophy: Basically anytime there is severe a problem, the pilot should assume control (the pilot should also monitor airspeed, keep his hands at the controls etc.):
FCTM:
Recovery from an approach to a stall is not the same as recovery from an actual stall. An approach to a stall is a controlled flight maneuver; a stall is an out-of-control, but recoverable, condition.
Note: Anytime the airplane enters a fully developed stall, the autopilot should be disengaged and the autothrottle should be disconnected.
