Looks like some status messages aren't getting set back to github
Looking at https://github.com/bazelbuild/rules_apple/commits/master and https://github.com/bazelbuild/rules_swift/commits/master, the majority of the recent commits show a yellow dot because some checks haven't completed. If you click thru to the buildkite pages, they appear to be done. So something seems to be keeping buildkite from delivering the final status back to github so the commits can have proper status.
Mhm. The yellow dot is a "/pr" commit status which should only be generated for pull requests by Buildkite. I'm not sure why it's showing up for commits in the master branch, too.
Maybe because the commit happened on a PR, and eventually a merge commit pulled it over to master?
