Way to get open database cursors?

Database toolbox Q here--if that ain't your kuleana, please ignore.

Say I've been "lazy" and/or "forgetful" and haven't been closing my cursors before wanting to close my database connection--is there a generic way to retrieve all open cursors so I can close them before attempting to close the connection?

Also, while I have "you" on the line: what's the difference between an "open" connection and a "valid" connection, i.e., the difference between a "false" result from isconnection and an error result from ping?

Thanks!

And one more: is there a (non-error-throwing) way to confirm that a cursor closure was successful? Thanks again!

To my knowledge the only solution is NOT to be lazy or forgetful (but happy to be proved wrong)

OK, but that still leaves me wondering, then: is a close(conn) failure the only way to detect a close(curs) failure? Thanks.

I've submitted "enhancement requests" for a cursor.isopen method and a connection.getOpenCursors method. They've been acknowledged, time will tell...
