Like it or not..... 
Application design. My personal oppinion is: It should only be allowed to use TRIGGER-FIRST.
The others are too complicated to use.
A simple way to handle this (I did it some years ago:
Write my own "trigger monitor" that was aware of how to handle TRIGGER-EVERY, by monitoring the queue.
This triggermonitor was started by a trigger-first, and it would wait until there was no more messages on the queue before it terminated. (It opened the queue with MQOO_INPUT_SHARED).
Another way could be to change the application to continue getting messages until the queue was empty....
I hope this helps.
Just my $0.02
