AFAIK, NetBSD does something called "copy-on-write", which basically means
that X copies of a program won't take up (size * X) amount of memory.
They will just take up (size) of memory.
(plus overhead, maybe)  If the program writes to the image, then, I think
it will "copy" it, and split that process's text space off.  I'm sure
someone else here could explain it better!  ;-)
