            Bug ID: 751846
           Summary: rtpjitterbuffer: With do-retransmission and
                    rtx-next-seqnum, wakes up the timeout thread for every
                    packet that arrives
    Classification: Platform

           Version: git master

            Status: NEW
          Severity: normal

     GNOME version: ---

update_timers() will remove the current timeout for the current packet and add
a new timeout for the next packet. That will unschedule the current timeout,
timeout thread wakes up, waits for the next timeout. Goto beginning.

This means we're doing a lot of context switches in the good case when no
packets are lost and no reordering happens.
