From #350:

It looks like the test tolerances are still too low (or there is a bug in the algorithm):
https://travis-ci.org/probmods/webppl/jobs/111013425

Across multiple tests, the distribution of the mean looks pretty sensible. The tolerances were too low before, but at 0.075 the tolerance (for the mean of nestedEnum5) is roughly 4 SD of the empirical distribution. I ran the test 5K times and only saw one test failure, which seems about right if we assume the distribution is Gaussian. I've bumped it up a little further (~4.5 SD) to give us more room. Sound OK?
