Right.  Getting that to work cleanly could be difficult

The problem is that once a transaction is accepted by one partition, it can
be very difficult to unwind.  That means that if part of a multi is on one
partition and another part is on another partition, you can't really do a
2-phase commit sort of thing since you can't roll back the part that worked
when you find out about the part that didn't.
