That should be much less relevant as people migrate to version 1.2, as
1.2 uses LISTEN/NOTIFY a whole lot less than earlier versions:

 1.  Number of events generated is cut in 1/2 because we don't
     generate NOTIFIES for confirmations anymore

 2.  When a thread is busy, it shuts off LISTEN, and polls.  That
     will cut pg_listener bloat further...
