[jira] [Commented] (MESOS-5909) Stout "OsTest.User" test can fail on some systems

Joseph Wu commented on MESOS-5909:
----------------------------------

We prefer ReviewBoard for all C++ and non-trivial changes.  

This is partly for Apache-Foundation-recommended reasons (they want to keep records of everything) and because the Github repo is a read-only mirror :)

> Libc call {{getgrouplist}} doesn't return the {{gid}} list in a sorted manner (in my case, it's returning "471 100") ... whereas {{id -G}} return a sorted list ("100 471" in my case) causing the validation inside the loop to fail.
> We should sort both lists before comparing the values.
