Comment (by exarkun):

 Note this PR didn't actually enable parallel test runs on CI because
 coverage collection is incompatible with trial's parallel test run
 feature.  The PR only made it possible for users to manually invoke this
 feature on their local runs.

 I've filed an upstream ticket, https://twistedmatrix.com/trac/ticket/9663,
 for implementing the behavior necessary to enable this on CI.  It would be
 nice to do so since it will probably make the whole test suite take
 roughly half as long (perhaps 20 minutes down to 10 for one full CI job).
