So, as a first step, I've committed a patch that just throws a hard
conflict.  I think we probably want to optimize this further, and I'm
going to work investigate that next.  But it seemed productive to get
this much out of the way first, so I did.

In studying this, it strikes me that it would be rather nicer if we
recovery conflicts could somehow arrange to roll back the active
transaction by some means short of a FATAL error.  I think there are
some protocol issues with doing that, but I still wish we could figure
out a way.
