Log Message:
Moved to transient transaction membership - subscribe is now good for one
transaction only, and there is no unsubscribe.  Added flag to protect
periods where subscription is unsafe.  Discovered that there's an issue
with subscribing to a transaction after a savepoint has occurred, but I
have no sensible way to fix it, that doesn't depend on whether savepoints
can be rolled back more than once, and won't make the transaction and
savepoint objects a lot more complex.  :(
