```
The PR in question refactors SQL code, but changed nothing in the coordinator. This same test passed on this branch in previous runs. Conclusion: test is flaky.
Theory: Travis has been overloaded of late. Perhaps Travis execution is slow and our test timeouts, optimized for a single-user Mac, are too aggressive for an overloaded shared system.
