To reproduce, you need to have MADs queued for processing on the local_list when
the sender unregisters (perhaps by killing the app).  You should be able to
widen the race window by adding a delay near the top of local_completions().
That will keep the MADs on the local_list for longer.  Alternatively, you would
need to have a lot of outstanding local MADs.
