To maximise the robustness of the functional tests we want to treat most
asset download failures as non-fatal to the test suite. Instead it
should just skip the tests which need that particular asset. The only
time aim to make it fatal is for 404 errors which are highly likely to
reflect genuine problems to be fixed.
We catch certain exception classes and handle them as transient errors,
but unfortunately it is proving difficult to predict what exception
classes urlopen() is capable of raising, with new possibilities being
discovered.
To provide a fail-safe, treat the generic Exception class as being a
transient error too. This may well mask certain genuine bugs, but it is
preferrable to prioritize running the test suite to the greatest extent
practical.
