Friendly ping @MarcoFalke and @sipsorcery :)

No objection to using the cache to avoid intermittent network issues. But the speedup was only ~2 minutes on a total runtime of 1 hour?

You're right. I've added "avoid intermittent network issues" to the PR description.

Seems like a good idea to me.

Won't the ci/windows_test_imagefile image be stored somewhere on the CI server for subsequent runs? I would have thought that would save more than 2 mins.

According to https://cirrus-ci.com/task/6075873112096768 the build took 5 min, so that is roughly the time you save. But with unit tests running for 10 min and functional tests for 40 min, it is saving not too much.

Avoiding intermittent network issues seems more useful.

Subsequent runs will use the cached image the same way as other jobs use the cached ci/test_image image now.
