There's already some complexity there for non-contig memory, but it's not
*very* complex :-)

I'm not sure how DUh does it... do they write a header on each page in
the dump?  Do they write a bitmap at the beginning of the crashdump
indicating which pages are actually in the dump (requiring you to count
up all the blanks to find the page.. ew)?
