 This might be a meta ticket or it might be a @jorbin ticket.

 When many commits land in core within a short (or not so short) period of
 time, a backlog of [https://travis-
 ci.org/aaronjorbin/develop.wordpress/builds pending builds] can build up
 on Travis, which means committers have to wait longer and longer to see
 the result of their commit. Sometimes interim builds are manually
 cancelled by users that have been given access by @jorbin.

 Ideally, any ''pending'' builds (builds that have yet to start) would be
 automatically cancelled when each new build gets triggered by a commit.
 That way, when a build completes, all interim builds will be skipped and
 the most recent build will begin.

 This works well for the WordPress project because we only have a single
 branch and don't need to worry about builds for other branches.

 Travis has [https://docs.travis-ci.com/api an API] that could be used to
 cancel pending builds when each new build arrives.

 Thoughts?
