originalproject's unit tests to attempt to reach some level of compatibility between the implementations. Currently
about80% of the unit test have been migrated and only 6 the test are not passing. The failing or erring tests are
mostlydue to, as yet uncommitted to differences, in the way the drivers work; once permanent decisions are made the
driverwill be fixed to conform or the test will be updated. Up until now the focus has been on features and
conformancebut I will be departing from that for a bit to do some performance analysis and enhancement before adding
anynew features.

consciousdecision not to support this because it seems to give the illusion of preparation when the server in fact
doesn'tsupport preparing multiple statements. Multiple statements are allowed in regular Statements.
