IMO: Allocate a block if there's space, something like the current 'badspot'
behaviour if the block can't be allocated (eg 'cause of a badspot ...)

While you're on the subject of new features, is there any hope of allowing
a loopback device onto /dev/mem (Yes the _character_ the device) or an
equlivent ?

It was one of the most obvious things to try for >1.2.13 when I wanted
to put a swap file onto the slow memory in an old 386...
