Well, that's true of all Lua programs, so yes, that's also part of the
Lua spirit. :)

I was thinking of the second option, something from scratch. For
example, get rid completely of the file system. Instead of explicitly
writing data down from RAM to disk, just use the swapping. Your programs
would create tables to store data, and put them in a global "storage
table". The OS would then swap them to disk/flash automatically when
running out of RAM, as needed. From program's point of view, they just
create tables and they are always available. When you shutdown, all the
data is swapped down to disk, and when you switch on the the data is
right there and state is maintained.
Crazy stuff like that.
