docs: // DialWithTimeout works like Dial, but uses timeout as the amount of time to
  // wait for a server to respond when first connecting and also on follow up
  // operations in the session. If timeout is zero, the call may block
  // forever waiting for a connection to be made.
  //
  // See SetSyncTimeout for customizing the timeout for the session.
