Correction for the fix for Bug 3508 - Persistent storage support breaks Linux compatibility.
A 2nd `make install' will fail attempting to create symlink libnvmemmory.so already created by 1st install.
Install should pre-emptively delete it.

The None Object
---------------
.. index:: object: None
Note that the :ctype:`PyTypeObject` for ``None`` is not directly exposed in the
Python/C API. Since ``None`` is a singleton, testing for object identity (using
``==`` in C) is sufficient. There is no :cfunc:`PyNone_Check` function for the
same reason.
.. cvar:: PyObject* Py_None
The Python ``None`` object, denoting lack of value. This object has no methods.
It needs to be treated just like any other object with respect to reference
counts.
.. cmacro:: Py_RETURN_NONE
Properly handle returning :cdata:`Py_None` from within a C function.
