 The reason is that 3.1 didn't try to shutdown amd(8) cleanly but 4.0 does.
 The old behaviour caused dead NFS mount points on my system which prevented
 the final unmount of all filesystem. Since "/etc/rc.d/amd" shuts down
 the daemon properly I haven't seen that problem.

 I've tried that in the past and it never hung for me. Can you please
 provide more details about your amd(8) configuration?
 
 I'm not sure whether there is a fix that fixed boht bugs except replacing
 amd(8) with an in-kernel automounter.
 
        Kind regards
