Test failures on PyPy - Githubissues

Currently some tests fail on PyPy with a rather confusing error message and traceback.
Example:
____________________________________________________ TestFullApp.test_inc_counter_app[6] _____________________________________________________

self = <devp2p.tests.test_full_app.TestFullApp instance at 0x000000010bc9ae40>, num_nodes = 6

    @pytest.mark.timeout(60)
    def test_inc_counter_app(self, num_nodes):
        class TestDriver(object):
            NUM_NODES = num_nodes
            COUNTER_LIMIT = 1024
            NODES_PASSED_SETUP = set()
            NODES_PASSED_INC_COUNTER = set()

        ExampleServiceIncCounter.testdriver = TestDriver()

        app_helper.run(
            ExampleApp,
            ExampleServiceIncCounter,
            num_nodes=num_nodes,
            min_peers=num_nodes-1,
            max_peers=num_nodes-1,
>           random_port=True  # Use a random port to avoid 'Address already in use' errors
        )
