I you've actually lost bits from the file, you're screwed.  Since we do
a garbage collect before snapshotting, every bit in the supposed dump
is sacred, every little one (and zero). At the top end of memory you're
going to be missing some relatively new objects that are being pointed
to by older ones. Dangling pointers are not allowed!

Basically you can usually rescue a lot from the changes log assuming it
wasn't also mangled somewhere along the line.
