 This test patch works great!
 I've connected, disconnected, restarted and reloaded very many times in 
 random order and nothing bad happens!
 
 If I kill my mpd4 (without touching pf) I get the debug log:
 
 pf: remove altq ng0. ...22 22 22
 
 I get always "22 22 22". No other numbers after serval restarts of mpd4, 
 pf and FreeBSD.
 
 Thank you for your promptly investigation!
