      • toMessageSet

                                        Utility.Condition cond)
        Run thru the given array of messages, apply the given Condition on each message and generate sets of contiguous sequence-numbers for the successful messages. If a message in the given array is found to be expunged, it is ignored. ASSERT: Since this method uses and returns message sequence numbers, you should use this method only when holding the messageCacheLock.
        Parameters:
        msgs - the messages
        cond - the condition to check
        Returns:
        the MessageSet array
