Uh-oh. This isn't the way I understood putNotify. It would be a disaster
for one client to initiate a putNotify trace on the same record, or even a
different record in the same lockset, as an ongoing putNotify trace. How
could you ensure that the two execution traces would not interfere with
each other?
