Comment(by phk):

 I have added code that does one retry in carefully limited circumstances
 (see above)

 You ideas about incremental backoff are relevant, but conflict with our
 policy of trying to protect the backend, rather than attack it, the
 assumption being that if it is flakey now, hitting it harder is not likely
 to make it any better.

 If you want to force retries, VCL has the return(restart) facility that
 will allow you to do that.
