Does inspect.getstack work on other Python implementations?

[Steven D'Aprano]

Anyone here use IronPython, Jython or PyPy?

Does inspect.getstack always work? Is it considered an implementation 
detail for CPython or something promised to work on any compliant Python 
interpreter?

I see that it doesn't even exist on Jython 2.5, does anyone know whether 
it exists in later versions?
