The pessimistic lock does that. If IBO can't get the lock, it won't let
the row go into Edit mode. You can catch the exception and use it to
inform the user that someone else is working on it.

OTOH, if you use the "quick transaction" approach with Read Committed and
WAIT, there will be no exception if the later transaction has a higher
transaction ID on the server. First to get the lock wins, others follow on
in "hit order".
