These kids who think that 256M of physical ram is *small* :-)
My first Unix machine had 128K of MOS memory, and we supported about
10-15 interactive users on it at a time, with a 30M
disk drive that was the size of a washing machine. Having /tmp in RAM
was a newfangled thing that came along later, but
with 30M of physical disk there, /tmp had to be small anyway!
