For interpreters that share state with the main interpreter, this points to the same static memory structure. For interpreters with their own obmalloc state, it is heap allocated. Add free_obmalloc_arenas() which will free the obmalloc arenas and radix tree structures for interpreters with their own obmalloc state.
Note that the free is only done if obmalloc used blocks is zero. If some blocks are used, it's not safe to free the memory since some extension might still be using it.
