If I understand correctly, Lisandro simply recommends loading the library
loading my refchecker.so utility code (basically a twenty-liner raising
the right diagnostics at the right times) using ctypes with the
RTLD_GLOBAL flag (which I didn't know about until I just now read the
ctypes docs).

Over to something else: Does anyone have an opinion on a choice between
these two:

 - I change Cython to always generate __Pyx_INCREF/DECREF/GOTREF/GIVEREF.
Whether to install the refcount nanny or not only affects the definition
of these macros (the latter two being noops when the nanny is not in
operation). I'm +1 on this one.

 - If the refcount nanny is not installed, generate direct
Py_INCREF/DECREF and do not generate GOTREF/GIVEREF.
