Uh-oh, I misunderstood your code. I didn't notice that you had unless
inside the lock too. I apologize.

I wasn't even aware of this issue MenTaLguY is talking about. I would
have thought that your second version worked, (as indeed it does in
1.8, although this behavior isn't advertized) although I still prefer
my explicit initialization beforehand for something like this.....
however, is that even a valid solution? After reading MenTaLguY's link
I'm not so sure...
