-// testSyncHooks coordinates goroutines in tests.
-//
-// For example, a call to ClientConn.RoundTrip involves several goroutines, including:
-//   - the goroutine running RoundTrip;
-//   - the clientStream.doRequest goroutine, which writes the request; and
-//   - the clientStream.readLoop goroutine, which reads the response.
-//
-// Using testSyncHooks, a test can start a RoundTrip and identify when all these goroutines
-// are blocked waiting for some condition such as reading the Request.Body or waiting for
-// flow control to become available.
-//
-// The testSyncHooks also manage timers and synthetic time in tests.
-// This permits us to, for example, start a request and cause it to time out waiting for
-// response headers without resorting to time.Sleep calls.
