Noticed a few potential issues while working on neighbour code: * `__exit__` only restores `pickle.load` but `hook.run_hook()` patched more APIs than that and they won't be restored. * Could the internal hook clash with a pre-existing ML global hook? Same with `__exit__`? * `wrapped_load` is dead code, so support for `max_acceptable_severity` likely never worked here.
