I don't agree here.  The point of having a dedicated dump device could be to 
not overwrite the state of the swap when dumping core.  In addition, a dump 
device could double as a place for suspend to disk if/when we implement this - 
in this scenario it would also be required that the dump device does not hold 
valuable swap data.
