while next (t) do

This doesn't work if false is a key.

Easily fixed by checking specifically for non nil keys:

while next(t) ~= nil do
	t[next(t)] = nil

However, another way to go about the "my submodules may have references..." is to use weak references (but then they'll have to check that their reference is still valid before using them).
