The book, "The Go Programming Language" has this simple goroutine

Here is one that uses receiveTimeout and OwnerTerminated:


Very nice, replacing Thread.sleep with receiveTimeout and getting 
graceful interruption for free. This also doesn't crash.

Cool. :)

Actually, it can be shorter by checking the return value of receiveTimeout:

      if (receiveTimeout(delay, (OwnerTerminated msg) {})) {
        return;
      }

I didn't use this method earlier because I was afraid an unexpected 
message might make receiveTimeout return 'true'. But I've tested just 
now: Only the expected OwnerTerminated makes it return 'true'.
