Changing

https://github.com/buriy/python-readability/blob/master/tests/test_article_only.py#L104:L104

to

    @timeout_decorator.timeout(seconds=3, use_signals=True)

the test is green but with caveats, it might bring.

Or changing the timeout library to https://github.com/bitranox/wrapt_timeout_decorator

See patch: wrapt_timeout_decorator.patch
