According to Marco d'Itri the /dev/md-* node _is_ removed if the command
'cryptsetup remove $NAME"' is used to bring down a crypto volume (I've not 
tested this myself).

But looking at do_stop() in /lib/cryptsetup/cryptdisks.functions, the only 
thing cryptsetup seems to do on shutdown is:
'losetup -d /dev/loop$minor'

So, maybe this is a cryptsetup issue after all?
