I still think that we can do that with finalizers. As long as each
object has a proper finalizer (i.e., a __gc metamethod), all we have to
do in case of errors is to call collectgarbage() to finalize what was
left.

(One small thing we could change in Lua is to automatically call a
full GC cycle whenever an error is caught.)
