       hold it afterwards.

(What it really does used to be completely different in Python 2
       and Python 3, with the Python 2 solution avoiding the spin-lock
       around the Py_InitializeEx() call.  However, after recent changes
       to CPython 2.7 (issue #358) it no longer works.  So we use the
       Python 3 solution everywhere.)

This initializes Python by calling Py_InitializeEx().
       Important: this must not be called concurrently at all.
       So we use a global variable as a simple spin lock.  This global
       variable must be from 'libpythonX.Y.so', not from this
       cffi-based extension module, because it must be shared from
       different cffi-based extension modules.  We choose

         extension is running the initialization in another thread.
         It is reentrant, so that a recursive call will not block, but
         only one from a different thread.

* then we grab the GIL and (Python 2) we call Py_InitializeEx().
         At this point, concurrent calls to Py_InitializeEx() are not
         possible: we have the GIL.
