[Date Prev][Date Next][Thread Prev][Thread Next] [Date Index] [Thread Index]

Two ideas:

1) You could explicitly lua_unref your table to clean it up.
2) Instead of storing your table directly in the registry, you
could store it in a weakly-valued subtable of the registry.  That way,
when the last reference outside of the registry table goes away, your
table is collectable.
