 // A send algorithm which adds pacing on top of an another send algorithm.
 // It uses the underlying sender's bandwidth estimate to determine the
 // pacing rate to be used.  It also takes into consideration the expected
 // resolution of the underlying alarm mechanism to ensure that alarms are
 // not set too aggressively, and to smooth out variations.
