Travis CI - stability?

Hey guys, just a follow up on what we were discussing recently: the CI jobs running on Travis CI are again failing, https://travis-ci.org/richfaces/richfaces now because of 50min limit after which the tests time outs. Since our tests usually passed in 30min, I'm afraid this is not issue we could influence much. That returns us back to the CI and stability, we had problems with CloudBees and we have problems with Travis CI now. One solution is migrating tests to other machine altogether - Jenkins on Openshift is one solution that comes to my mind. Is it too drastic solution, should we rather "fix" Travis CI somethow?
