We have patches for xa support pending, but have not committed them yet.
Our 2PC support doesn't allow a full XA implementation because full XA
allows multiple transactions to run in parallel on the same resource and
allows other threads to join an already running transaction. The
question is whether application servers and transaction managers do
this by default and whether it can be disabled. Initial research shows
our support may be good enough for practical purposes.
