OK. I thought I saw mention of delete on close for all exclusive queues
when searching for info, but perhaps I misunderstood, or maybe someone
else got it wrong.
The queue is also there before the application first starts, which is
another reason for my confusion. I thought flags like this was generally
only set on creation...

Exclusive auto-delete queues are handled slightly differently from
non-exclusive auto-delete queues. The description of that may have been
confusing.

Most things are. The exclusive flag is slightly different. It is like a
lock. If you declare the queue with exclusive=true, and the queue is not
currently owned exclusively by any other session, then you will set the
owner lock on it. When your session ends the lock is released (but if
the queue is not auto-deleted, the queue remains).
