[issue8020] Crash in Py_ADDRESS_IN_RANGE macro

[Tim Peters]

Note that nothing in obmalloc is _intended_ to be thread-safe.  Almost all Python API functions make the caller responsible for serializing calls (which is usually accomplished "by magic" via the GIL).  This includes calls to all facilities supplied by obmalloc.
