The small object allocator uses large mmap-allocated arenas of 256 KB (IIRC) and carves small objects out of it.  So unless the pointer returned by PyObject_Malloc() has its bounds set manually using one of the intrinsic functions (*), MPX would believe the bounds of small objects are the bounds of the 256 KB arenas containing them, right?

(*) I'm assuming __bnd_set_ptr_bounds()
