That is quite true. I had not realized that it was possible for this to
vary within a MySQL database at the time I put that flag in.
I believe MySQL is the only database people are likely to use with HDBC
(even Sqlite has universal transaction support) that has this issue, so
I would really encourage the community of MySQL users to come up with
the API that would be most helpful in this situation, and as I said, I'm
happy to add it to HDBC.
