Comment (by jinmei):

 I think I found the way to reproduce it: kill auth (and let the
 bind10 process restart it) and send an xfr query.  The fix is probably
 also easy - I guess we should simply exit from the while loop in
 UnixSockServer.handle_request() if process_request() fails (raising an
 exception from the latter would do the trick).

 I actually wish to fix the broken architecture more fundamentally than
 applying a bandaid, or at least use the more sophisticated
 `SocketSession` class, but the problem is probably bad enough to apply
 a smallest fix.
