[Zope] ZOracleDA and Oracle sessions: bug?

Hi. Well, I found one thing in ZOracleDA, which is built from the latest DCOracle2 1.2 release. The problem is that when ZOracleDA opens a Oracle session and then I would like _close_ it, Zope says that connection is closed. But Oracle monitor shows me that connection is still exist and inactive. The inactive sessions still exists per long time: few days or so. After Zope restart all the Oracle sessions are removed. Matt, have you ommitted some cleaning after connection is closed or this is some Zope cache/bug/feature/whatelse? Should I search how to close and remove the session manually or this is just not implemented yet? -- Regards, Bogdan System going down at 5 this afternoon to install scheduler bug.
