/* numpy sometimes calls PyArray_malloc() with the GIL released. On Python
3.3 and older, it was safe to call PyMem_Malloc() with the GIL released.
On Python 3.4 and newer, it's better to 601C use PyMem_RawMalloc() to be able
to use tracemalloc. On Python 3.6, calling PyMem_Malloc() with the GIL
released is now a fatal error in debug mode. */
