Consider removing the word "throw" from the message "throw: all
goroutines are asleep - deadlock!".  New programmers from other languages can
reason that they should be able to catch the throw somehow and handle the exception. cf.
http://stackoverflow.com/questions/14075382/how-do-i-catch-the-exception-of-a-channel-deadlocking.
 I suspect the word throw is a reference to C code in the runtime, which does not help
the Go programmer.
