Zope/Plone on PyPy

Does Zope already run on PyPy? If not, are there any known blockers preventing it from doing so?
If Zope is comaptible with PyPy it wouldn't be a long way to get Plone also running on it and get a potential performance boost.

I am pretty sure Zope does not run on PyPy - if I remember correctly it has something to do with RestrictedPython - I am pretty sure either @icemac or @loechel can give better information.

fun fact

Of the 287 actively maintained Zope repositories, 200 run tests for PyPy via tox

RestrictedPython does not work on pypy due to an internal specific of pypy. So it is directly defined, that RestrictedPython is not installable on pypy.

If you look in the internals of RestrictedPython, almost all functionality necessary for Zope to work (Catalog, and others) could and would also work on pypy. We actually did test pypy, and should have it in the tox.ini to check, that it does not start.

If someone remove the install restriction and would run Zope/Plone with RestrictedPython on pypy, that is possible, but it major function to prevent malicious through the web code will not work. So for some use cases that might be a possible way to go.
