A friend of mine has recently implemented a ``mini-dump'', which is
primarly a conceptional implementation that I need to do some clean-ups
on my spare time. I think in order to have a successful ``kernel dump''
we need to keep least dependency on VM structures (and allow users to
switch to a full dump when need).
