[tvernum]

These all seem to be caused by a temporary (?) Docker issue.

The test has failed 15 times out of 13,123 builds in the last 4 weeks, and 2 out of 6,453 in the last 2 weeks. Whatever went wrong no longer seems to be a significant issue.

Will keep the ticket open in case the problem comes up again, but if it's quiet for a few weeks I'll close it.
