Since Jython and IronPython are conforming Python implementations, and 
Guido has started making policy decisions specifically to support these 
other implementations (e.g. the language feature moratorium, PEP 3003), I 
think we can assume that this is a documentation bug.

However, a Python implementation that always returned 0 for 
sys.getrefcount would technically satisfy the word of the documentation, 
if not the spirit.
