* minimize unnecessary signals. One simple and correct algorithm is to signal some other waiter
   * with a satisfied guard (if one exists) whenever any thread occupying the monitor exits the
   * monitor, either by unlocking all of its held locks, or by starting to wait for a guard. This
   * includes exceptional exits, so all control paths involving signalling must be protected by a
   * finally block.

	// Exit conditions:
	//
	// 1. If a writer.write() returns false, select loop below exits and
	// closes `doneCh` to indicate to caller to also exit.
	//
	// 2. If caller (Evaluate()) has an error, it sends an error
	// message and waits for this go-routine to quit in
	// FinishWithError()
	//
	// 3. If caller is done, it waits for this go-routine to exit
	// in Finish()

<p>
Even if <code>main</code> observes <code>g != nil</code> and exits its loop,
there is no guarantee that it will observe the initialized
value for <code>g.msg</code>.

In all these examples, the solution is the same:
use explicit synchronization.
