Having complete save/restore functionality is quite interesting.
It's also more involved than just dumping the above info to a file.
You have to save the state of all devices, timing framework, info
about open files, and other info.
I don't think it's a good idea to enhance plex86 architecture
to handle this yet. There are other more pressing and modular
tasks we should complete first.
There is also someone who is interested in helping out with this,
who has done this before. Best to make use of their work already
done and defined in this area.
