A "continue" statement begins the next iteration of the

When the Go tool sees that one or more Go files use the special import

Worse, there is no guarantee that the write to <code>done</code> will ever
be observed by <code>main</code>, since there are no synchronization
events between the two threads.  The loop in <code>main</code> is not
guaranteed to finish.
