Travis CI - Job Exceeded Maximum Time Limit

Most Travis CI jobs are failing with the following error message.

The job exceeded the maximum time limit for jobs, and has been terminated.

Travis apparently has a hard 50 minute limit that will cause jobs to timeout.

There is some additional time for setting up the container that is counted in this hard 50 minute limit that is not reported in the UI. So even if a build says it took 44 minutes with a timeout, it likely in fact did hit the 50 minute limit.

Here are some examples of these failures.

This is a separate issue from the "Storm slots didn't shut down" issue that is tracked in a separate PR.
