Travis has rolled out a new feature (beta) that will automatically cancel builds when a new build appears in a branch. This can help shorten build time when someone commits a small number of small changes to an open PR. This seems like a good feature of have on PRs (but not master) and can help with "push spam".

already enabled! (this commit is for putting in our own auto-cancel).
note that you need to enable it on your own branch. I suppose we could document that.

actually its on master as well. because if you have an open PR, then you push again, we need and want it to cancel the previous one (on master).

There is no way to tell what other repos settings are on Travis, so I though I would check that it was on. Might help a lot.

yeah if you want to create an issue about updating: http://pandas-docs.github.io/pandas-docs-travis/contributing.html#test-driven-development-code-writing
IOW about CI interactions would be fine. (IOW the meaning of 'green' builds and such).
I find newbie are confused by this actually.
