Comment(by phk):

 There will always be a race, where the backend closes after we sent the
 request, and the more distant the backend, the more likely the race.

 Retrying is the sensible thing to do, but I am not convinced that it is
 always the sensible thing to do.

 For one thing, we should only retry if we got a recycled backend
 connection.

 But once we retry, we may get another recycled backend connection, so how
 many times do we retry ?

 Input welcome...
