  Huh? In your original post about static depth locking you say:

<GMC>
Here is (what I consider) to be an extremely sensible proposal from
Alan Babich (from a few months ago).  He basically says that if you
are going to do depth locking, it should be static, i.e. it should
be a lock on the current members of the collection.  If you MOVE
things into and out of collections (because you have the appropriate
lock tokens for the appropriate collections), it has no effect on
the locks on those resources.
</GMC>


Lock the CURRENT members of the collection.

I believe that is what John was commenting on.

This is giving me a headache :-)
