Can this change be simplified further? Vis:

	o	save an sbrk() call
		at the start to get the current
		top of heap

	o	call  sbrk () at the display time
		time and use that to compute
		the size.

Also can the nasty bit of math used to make the computation be pushed
into a function somewhere?

I think your proposed change just needs to be pushed a little bit
further so that all the nasties are eliminated :-)

	enjoy,
