I hadn't been following the discussion closely enough to know what the
problem is. But "cancel the current transaction" is far outside the
bounds of what sinval events are supposed to do. If you try to do that
we'll forever be fighting bugs in code that expected
AcceptInvalidationMessages to do no more than invalidate cache entries.
