Chris Nauroth commented on MAPREDUCE-5080:
------------------------------------------
There are failures in {{testPoolSize}} and {{testPoolLimits}}. See below for
stack traces. These tests have multiple assertions about some things that are
non-deterministic in the thread pool sizing logic of {{ContainerLauncherImpl}}.
Running on Windows happens to expose the race conditions.
