Research direction

Reproduce the leak with array_simpl_patched.zip, close the binary, and run get_memory_usage_info() to observe the active BinaryView count. Trace the malformed-binary cleanup path; done means closing the binary no longer leaves the reported BinaryView objects active, including the differing counts seen in versions 5.0 and 4.2.
