+Subject: [PATCH] Port twisted.deferredruntest to Twisted >= 15.1.0
+
+Twisted 15.1.0 removes the compatibility import of _LogObserver in
+twisted.trial.unittest.  This is unfortunate for us, but it's what we
+get for using an internal interface.  It at least still exists in
+twisted.trial._synctest, so we can get it from there.
+
+Twisted 15.2.0 adds the new twisted.logger framework, which requires a
+slight adjustment to run_with_log_observers.  There's no longer a
+supported interface to get hold of all log observers, but since we're
+already using an internal interface (see above), what's one more?
+
+This passes "make check" with the current release, Twisted 15.3.0.
