Frequent test failures

[BridgeAR]

Node.js runs the watchify test suite using CITGM (https://github.com/nodejs/citgm) as smoke test to identify unintended breaking changes in Node.js. We relatively frequently receive errors from watchify that seem like flakes:

https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/2142/nodes=osx1011/testReport/junit/(root)/citgm/watchify_v3_11_1/ (available ~7 days).

It would be great to get these fixed so that we ran rely upon the test outcome!
