Jython/Python do not specially handle tail call recursion, a stack
overflow is a definite possibility when recursion is used.  This is a
deliberate design choice by Guido van Rossum, see
http://neopythonic.blogspot.com/2009/04/final-words-on-tail-calls.html.
 It might be a good idea to revisit this code to see if we can use an
iterative approach (which is the more common idiom in Python).
