I vividly remember pulling my hair out over BuildHive (i.e. the Java-based Jenkins alternative to Travis) failures that turned out to be resource-related: I simply overloaded the BuildHive node.

So I assumed that the problems Lars referred to would not be problems of Git, or the test suite, but of overwhelming a free service with an unreasonable load.

I would like to caution against overloading Travis. They are really nice to us, we should try to be nice to them, too.
