singleflight: fix flaky TestForget There can be a race condition in current TestForget, that said when "close(secondCh)" is executed, the second goroutine will be finished immediately, causing the third "g.Do" is evaluated. To fix this, we change to use "g.DoChan" for both second and third. In second, we block to make sure it's still running at the time we call third. after then we unblock second and verify the result. Fixes golang/go#42092 Change-Id: I980fdf109a531e2b7a74c8149b4fcaa338775e08 Reviewed-on: https://go-review.googlesource.com/c/sync/+/263877 Trust: Cuong Manh Le <email@example.com> Run-TryBot: Cuong Manh Le <firstname.lastname@example.org> TryBot-Result: Go Bot <email@example.com> Reviewed-by: Bryan C.
