-  o Minor bugfixes (testing):
-    - Avoid intermittent test failures due to relying on hidden service
-      introductory point creation within 5 seconds of real clock time.  The
-      time limit for the test has been increased to 500 seconds, which may
-      still result in intermittent failures (e.g. if the system doing the
-      testing enters sleep/hibernation or experiences some other clock jump).
-      However, this should elliminate test failures currently happening on
-      developer and CI systems.  Fixes bug 25450; bugfix on 0.3.1.3-alpha.
