Promise chaining example
// `promise` is some operation that may succeed (fulfill) or fail (reject)
var newPromise = promise.then(
function () {
return delay(1000);
},
writeError
);
// If `promise` fulfills, `newPromise` will fulfill in 1000 ms.
// If `promise` rejects and writing to the error log succeeds,

Generalized promise retryer
"use strict";
// `f` is assumed to sporadically fail with `TemporaryNetworkError` instances.
// If one of those happens, we want to retry until it doesn't.
// If `f` fails with something else, then we should re-throw: we don't know how to handle that, and it's a
// sign something went wrong. Since `f` is a good promise-returning function, it only ever fulfills or rejects;
// it has no synchronous behavior (e.g. throwing).
function dontGiveUp(f) {
return f().then(
undefined, // pass through success
