Ah.. thanks for the clarification. Is this duplication "hard" or "soft"?
i.e. under low-memory conditions, do these duplicated pages actually reduce
the hard limit of VM available, or just imply that using that last bit of
memory will entail greater paging overhead (because it has to do more cleanup)?

Does this mean that having a swap partition less than or equal to RAM is now
effectively pointless?
