You're saying that in a new version of the driver, it will be possible
to setup HOLD_CURSORS_OVER_COMMIT by default in a connection, without to
configure each new Statement, aren't you?

And what's the real cost of memory? Because I use also other RDBMSs/JDBC
drivers and I don't experiment any problems with memory usage, either in
medium/large systems, with more than 500 (up to 1000) users
simultaneosly using a Servlet system.
