In principle, it can be done since the Lua API accepts a memory
allocator. Like you've said, it is tricky to handle userdata.

I've experimented with LPSM to make a Lua state persistent across
invocations of the interpreter. It worked reasonably well for a while.
The LPSM library is available at http://freshmeat.net/projects/lpsm/
but it does not seem to work on modern systems. I'd love to hear about
a modern replacement.
