I'd call a client that requires a LOCK before GET a poor implementation
(if it only wants to read the file). A LOCK doesn't guarantee you the
"youngest" revision any more than GET. All it guarantees is that nobody
changes the resource between the LOCK and the GET (so you win exactly
nothing compared to doing the GET right away).
