MSA in the LAM hold is around 3000'. Above MSA an immediate manouevre is not called for according to the SOPs I adhere too.
I am suprised that by reading other replies that you had not understood that there is a difference in response depending on whether one is above or below MSA.
I hope, should you be unfortunate enough to have a GPWS warning, that your lightening fast 'common sense' thought processes will be enough to save your life should the warning be real.
