Why?

We do already have ``virtual swapping'', but it's not controllable.  I
thought of this as one of the (few :) things that Silicon Graphics got
right: they allowed for a fine-grain control between ``eager'' and
``lazy'' swap.  All we've got by now is lazy swap, this is less waste
of resources, but you always risk a random process being killed due to
running out of swap.
