After allowing for the rather larger run-time system, if an application
could have been written in C, the Prolog version shouldn't need a lot
more memory than the C version.  About the worst that can happen to you
is manipulating sequences of characters:  where list-of-integer/vector-of-byte
is 8/1, but that's rarely the bottleneck.  I generally run Quintus Prolog
on a Sun-3 with "limit datasize 2M".  Any time that's not enough it usually
means it's time to take the hacks out of my code.
