Bug Description

This test fails if run on a slowish machine:

ERROR: We test that a mis-configured default_store causes the API server

STDOUT: Unable to increase file descriptor limit. Running as non-root?

Changing --await-child=1 in the code below to --await-child=3 allows the test to run ok.

    def test_unsupported_default_store(self):
        We test that a mis-configured default_store causes the API server
        to fail to start.
        self.default_store = 'shouldnotexist'

        # ensure failure exit code is available to assert on
        self.api_server.server_control_options += ' --await-child=1' <<<

        # ensure that the API server fails to launch

I can confirm that we've seen this fail sporadically on the Jenkins test vms as well.
