However, this is incorrect and can occasionally cause issues if you happen to have bad timing. First peer1 or peer2 may still be in use depending on the test and timing. Second we really should only be closing the read side and/or write side depending on if the test is receiving or sending. But, really none of this is needed just remove the shutdown calls.
