How serious is that power-of-two waste - in that is it then free for the next allocation to be taken from (ie if I then request 32-18 = 14Mb will it not 'allocate' any more), or is it really that bad? If so, what's the point? Surely it's no slower to allocate to the nearest word? ABW --- COMPUTER: We are in position over the Rebel homeworld.
