/* _PyArena_New() and _PyArena_Free() create a new arena and free it,
   respectively.  Once an arena has been created, it can be used
   to allocate memory via _PyArena_Malloc().  Pointers to PyObject can
   also be registered with the arena via _PyArena_AddPyObject(), and the
   arena will ensure that the PyObjects stay alive at least until
   _PyArena_Free() is called.  When an arena is freed, all the memory it
   allocated is freed, the arena releases internal references to registered
   PyObject*, and none of its pointers are valid.
   XXX (tim) What does "none of its pointers are valid" mean?  Does it
   XXX mean that pointers previously obtained via _PyArena_Malloc() are
   XXX no longer valid?  (That's clearly true, but not sure that's what
   XXX the text is trying to say.)

_PyArena_New() returns an arena pointer.  On error, it
   returns a negative number and sets an exception.
   XXX (tim):  Not true.  On error, _PyArena_New() actually returns NULL,
   XXX and looks like it may or may not set an exception (e.g., if the
   XXX internal PyList_New(0) returns NULL, _PyArena_New() passes that on
   XXX and an exception is set; OTOH, if the internal
   XXX block_new(DEFAULT_BLOCK_SIZE) returns NULL, that's passed on but
   XXX an exception is not set in that case).

 * _PyArena_Malloc()).
 * Note that pointers obtained via _PyArena_Malloc() must never be passed to
