When a Ruby program terminates, all threads are killed, regardless of 
their states. (pickaxe2 p. 137)

It seems strange to me that the thread would get killed at the same 
point every time.

...you can wait for a particular thread to finish by calling that 
thread's Thread#join method.  The calling thread [e.g. your main 
program] will block until the given thread is finished...If you don't 
want to block forever, you can give join a timeout parameter...
