as I understand it (and am practicing it), the dbi is created by one transaction
and remains valid after that transaction commits until it is either explicitly
closed or the environment dies. What *is* somewhat awkward is the fact that it
can be a read transaction that creates it. In my application, I am creating a
dbi handle for each (sub-)database using a short transaction for just that
purpose and then save it somewhere.
