i changed it so it at least says "Unregistered users cannot post on this thread". This matches the same message when a board is so locked, and gives a nominal reason to people who wonder why it is locked.
The link "Show All Details" gives the details of who and why. Though this is not obvious to the novice, I don't thin it's a big deal - and it is the right place for it. If anyone disagrees I could perhaps make it so that the permission lists shown in "Show all details" also appears when a "this thread is locked" message ever appears.
