That's strange, because the patch is really pretty simple. It works the
same as before, unless you change process IDs between calls to
db_Main(). It has been working well on a moderately large site where we
use transactions in the same way you're showing.
Are you overriding db_Main() in your base class? One caveat here is
that I use Class::DBI 0.96, but since this is an Ima::DBI change, that
doesn't seem likely to be the problem.

That's the most common problem. If you have any setup_table() calls,
they do make a connection during startup.

That works too. I just thought this Ima::DBI approach was a lot
simpler, since it doesn't require you to change your code.
