[issue22193] Add _PySys_GetSizeOf()

[Martin v. Löwis]

Martin v. Löwis added the comment:

Christian: I don't see why 24 bytes overhead sounds strange. GC_Head is

typedef union _gc_head {
    struct {
        union _gc_head *gc_next;
        union _gc_head *gc_prev;
        Py_ssize_t gc_refs;
    } gc;
    double dummy;  /* force worst-case alignment */
} PyGC_Head;

which happens to be 3*8=24 bytes on a 64-bit system.
