Ooh, you're good.  I hadn't thought of that.  Off the top of my head,
I think it may well mean that running more than one Lua state at once
(meaning concurrently, in separate JVM threads) is a bad idea / will
not work / will get corrupt results.  That particular use is rather
embarrassingly clunky and hacky, but it should be straightforward
enough to change if it does turn out to be a problem.

Thanks for very speedily finding a bug, or at least an embarrassment
that I should tidy up.  I will think on it.
