commit 72ea4a8f081318c60c460cef5d9daf55e399c434
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date:   Mon Sep 11 13:48:39 2017 -0400

    Extract the important parts of the run-pending-timers function.
    
    Our unit tests will need this, so that they can simulate advancing
    time without getting libevent involved.
