This may be where you go off base. All the "deleteSomething" messages 
are sent immediately *before* the object is deleted. It notifies you 
that a deletion is about to occur.

Locking messages stops all of them until messages are unlocked again, or 
until the handler ends. Messages always resume on idle.

The rev-related messages aren't sent during your handlers anyway (well, 
not most of the time, there could be rare exceptions.) When you lock 
messages in a handler, the lock is only effective within that one handler.

If your handler calls other handlers, then the lock on messages will 
remain effective until the original calling handler ends, or until 
either of the handlers unlocks it.
