Why is swap zero bytes? I know it is not needed, but still, after some

Eh, my 4.5 year old Tuxedo has a 2 GB swap, 32 GB of RAM and swap is still 
(and has always been) 0

I go back to the pre swap days, when overlays were used. This system had a head per track disk where portions of the program were stored and copied into memory as required. This was on Data General Nova computers and they had a HUGE 256K or 512K disk! Yep, that's right, a 1/4 or 1/2 meg disk, though that was 16 bit words, not 8 bit bytes. Later systems I worked on, Data General Eclipse had memory bank switching, what was called expanded memory in the PC world. Later on, I was working with virtual memory on VAX 11/780 computers.
