this is not the same as under CPython2.7.9
i am writing a script that mainly using multiprocessing to do huge calculation
for speed reason i have precalculated some factors as dict
i want to share the dict(~900MB) within processes, manager.dict() use too much mem(i have no idea why)
so i decide to use ctypes; but it complain
TypeError: cannot create weak reference to 'dict' object, at https://bitbucket.org/pypy/pypy/src/76611312113ea3ba08c89bc40dca460949743d1b/lib_pypy/_ctypes/primitive.py?at=default#cl-56
it runs well under CPython2.7.9, should it have the same behavior?
