on a sidenote, someone I know has the same max stack size as me
(8192), and with slightly different versions of 1.8.1, on debian he's
got a SystemStackError calculating ackermann(3,7), while I can even
calculate ackermann(3,8). 
I'm not a unix guru,  may be possible that there are other things to
look for?


the ackermann implementation is:
def ackermann(m, n)
    if m == 0 
	n + 1
    elsif n == 0 
	ack(m - 1, 1)
    else
	ack(m - 1, ack(m, n - 1))
    end
end
