Subject: tail recursion

Greetings, Ruby hackers!

I have a small implementation question: does Ruby support tail
recursion optimisation a la Scheme?  e.g, if I write the following:

	  def factorial x
	    fail if x < 1
	    (x == 1) ? x : x * factorial(x - 1)
	  end

Am I going to get at most one stack frame or zillions?
