-Debugging deadlocks
-===================
-
-Between the numerous Pykka threads and GStreamer interactions there can
-sometimes be a potential for deadlocks. In an effort to make these slightly
-simpler to debug Mopidy registers a ``SIGUSR1`` signal handler which logs the
-traceback of all alive threads.
-
-To trigger the signal handler, you can use the ``pkill`` command to
-send the ``SIGUSR1`` signal to any Mopidy processes::
-
-    pkill -SIGUSR1 mopidy
-
-If you check the log, you should now find one log record with a full traceback
-for each of the currently alive threads in Mopidy.
