If I were to do something like this I would first try to only put the heap
and referenced off heap binaries to disk. This should be the majority of
the memory footprint and will allow all process meta data (links, monitors,
registry etc etc) to remain unaffected. The question is what to do about
the stack which could contain pointers to code that has been changed while
the process was hibernated.
