FYI Reilly: the meeting spreadsheet seems to connect your name to signin, and I think this is a big part of it. In-progress in https://chromium-review.googlesource.com/c/chromium/src/+/1148471, but some stuff doesn't build yet (though a lot of stuff builds & passes tests)

Marking this as started since you have a patch underway.

morlovich@, any update here? are you blocked on reviews?

morlovich@ appears to have a WIP patch here:

https://chromium-review.googlesource.com/c/chromium/src/+/1148471

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/44cd1928239236ba639176ddbbd9fb83606ed819

commit 44cd1928239236ba639176ddbbd9fb83606ed819
Author: Maks Orlovich <morlovich@chromium.org>
Date: Fri Aug 10 15:32:21 2018

IdentityTestEnvironment: explicitly track pending & available token requests

... Rather than relying on them to be sufficiently close to each other
that there isn't much event loop activity.

This is needed for upcoming port of GaiaOauthClient to Network Service
(and hence mojo), which requires tests to spin the event loop in a lot
more places than before to deliver fetch results, making it hard to
ensure that HandleOnAccessTokenRequested and WaitForAccessTokenRequestIfNecessary
get delivered in right order.

S13n: Port GaiaOauthClient to SimpleURLLoader

URLFetcher will stop working in the browser process with
advent of Network Service, and SimpleURLLoader is the replacement
API for most clients.
