There was an JDBC-based *attempt* at an XA handler; it wasn't fully
functional, which essentially means it wasn't really XA.
When the 2PC discussion was going on, it definitely came up in the
discussion that this was a prerequisite to doing XA properly. It
might not be forcibly necessary in the strictest sense, but 2PC is
certainly one of the normal means for synchronizing distributed
transactions...
