The POA ensures that the semantics of local objects are identical to
those of remote objects. This means that clients can be forwarded to
other objects, objects can be activated on demand and exciting things
like that. Unfortunately, this means that calls to local objects have
to do a bit of mutex locking, etc., to protect against concurrency
problems.

you want them. Are you out there David?...
