Does commit retain really work?

Hello, everyone:

I'm testing the new BDE parameter for InterBase: COMMIT RETAIN, but I can't
get it to work. My SQL Monitor keeps on showing me isc_commit_transaction
for explicit transactions. I have tried changing DRIVER FLAGS to 0 & 4096
to enable and disable commit retain behaviour for implicit transactions,
but with no results. Could anybody shed a light into this?
