0.22.0: test_timeout_subsequent times out

[mtelka]

While packaging httplib2 for OpenIndiana I noticed the test_timeout_subsequent test fails as follows:

___________________________ test_timeout_subsequent ____________________________
tests/test_other.py:137: in test_timeout_subsequent
    assert response.status == 200
E   AssertionError: assert 408 == 200
E    +  where 408 = {'content-type': 'text/plain', 'status': '408', 'content-length': 15}.status
        Handler    = <class 'tests.test_other.test_timeout_subsequent.<locals>.Handler'>
        _          = b'Request Timeout'
        http       = <httplib2.Http object at 0x7fffac2d0eb0>
        response   = {'content-length': 15, 'content-type': 'text/plain', 'status': '408'}
        uri        = 'http://localhost:60947/'
