My guess: it is generally measured in addressing units. This means
bytes on byte-addressed machines and words on word-addressed machines.

Probably due to its Lisp Machine heritage; real Lisp Machines, AIUI,
were word-addressed. I don't know enough about OpenGenera to know
whether it's a real virtual machine emulator the way the display
implies; if so, it will of course act like the machine being emulated;
if not, it's probably just easier to pretend.
