Code review comment for ~jawn-smith/autopkgtest-cloud:long-software-properties

I think this should be OK, but can you confirm that making the test long lets it complete, and it's not hung?

I'm seeing quite some variation in the history with test durations. That could be due to server load causing the tests to run slower sometimes, but I'd ideally like to know that it's not actually that there's a race condition which means we can hang forever - in which case making the tests 'long' would just hold up nodes for more time.

If you can't reproduce the timeout then the alternative strategy would be to merge this and someone agrees to watch the results for a bit to confirm they are consistently green now.
