Work has progressed nicely and I have been migrating the original project's unit tests to attempt to reach some level of compatibility between the implementations. Currently about 80% of the unit test have been migrated and only 6 the test are not passing. The failing or erring tests are mostly due to, as yet uncommitted to differences, in the way the drivers work; once permanent decisions are made the driver will be fixed to conform or the test will be updated. Up until now the focus has been on features and conformance but I will be departing from that for a bit to do some performance analysis and enhancement before adding any new features.

This so far this has been conscious decision not to support this because it seems to give the illusion of preparation when the server in fact doesn't support preparing multiple statements. Multiple statements are allowed in regular Statements.
