No, the guard object does not need to be special in any way.  As for
recursive locking, I honestly don't know, but it's a very good question
which I'll forward to our runtimes group (and will update the 
documentation
with the response I get).

BTW, can you re-spin your patch (examining root instance methods when 
sending
messages to 'Class') against the mainline now that all the stuff is in? 
 Thanks.
