-Fix test failures caused by some build machines running more slowly than
-expected, which manifest like this:
-
-------
->       raise FailedHealthCheck(message)
-E       hypothesis.errors.FailedHealthCheck: Data generation is extremely slow: Only produced 4 valid examples in 1.08 seconds (1 invalid ones and 0 exceeded maximum size). Try decreasing size of the data you're generating (with e.g.average_size or max_leaves parameters).
-E       See http://hypothesis.readthedocs.org/en/latest/healthchecks.html for more information about this. If you want to disable just this health check, add HealthCheck.too_slowto the suppress_health_check settings for this test.
