Cuong Manh Le 67f06af15b 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.
