Test failure looks unrelated to the changes in the PR:

  Installing : drupal6-openshift-features-forums-1.9.1-1.git.0.30511a5.   83/84 
E, [2015-09-29T19:18:36.163127 #9780] ERROR -- :

Weird—it timed out in the same place:

Failed on the following, which was fixed by https://www.github.com/openshift/rhc/pull/703:

Bundler could not find compatible versions for gem "net-ssh":
  In Gemfile:
    rhc (>= 0) ruby depends on
      net-ssh (< 2.9.3, >= 2.0.11) ruby

    rhc (>= 0) ruby depends on
      net-ssh (3.0.1)

[test] again.

I will tag this PR to have the gear extended tests run on it once #6291 is merged.

@tiwillia, I have this way old cleanup PR. Looks like the last test run succeeded—think it's worth merging?

[tiwillia]

I'm wary to merge anything we don't explicitly need at this point, but this PR is rather harmless.

Lets [merge] it.
