No such guarantee! It will be collected whenever Lua feels like doing
a collection - there is no concept of immediate finalization.

So in general, better to close the handle immediately and wrap it all
up in an exists() function.

(Deterministic finalization _would_ be a cool feature, and naturally
it has been discussed before)
