You do mean Haiku, right?

(I can't seem to transfer a BFS image to USB here,
not in Windows with flashnul, nor in Haiku with dd.
'dd' to a raw USB device times out.)

I suppose virtual memory and the page file mechanism
could be extended to actually save pages continously,
eventually covering all pages. Perhaps aided by some
kind of checkpoint API. It might have to make sure that
the dirty set of pages for a process are cloned 
(copy-on-write?) and then written to disk as a set,
to avoid inconsistencies.

One might want to use a separate dedicated disk for
this purpose.

I'm sure there are security concerns though.
