Indeed.  From that point of view it would make sense if CPython and
PyPy (to start with) co-operated in writing down a list of things in
CPython that cannot be reasonably implemented on PyPy.  We have
already two pages listing differences, which would be a good start if
it was brought to the attention of CPython developers; but it only
outlines general lines, and not, I think, "sys.getrefcount() is not
available on PyPy at all".

A bientôt,
