  *     Zero is used as swapped, 1 is used as in memory.

+ *     TODO:
+ *     Write a simple-big module for systems like 68000 where it may be worth
+ *     writing out only the used areas of memory and fast zeroing the rest
+ *     on switches. It makes no sense to support it here because to do that
+ *     well we want to support a simple first fit allocator for swap ranges
+ *     so our swap isn't huge and empty.
