Well, if we did want to change this it would be far easier and safer to
do the other thing (ie, set QueryCancel upon noticing a write failure).
The question is whether doing either one is really a material
improvement, seeing that neither is going to provoke an abort
until/unless the backend actually tries to write something to the client.
