It is a static, global, fixed size array, see yourself:
struct method_cache_entry {
unsigned int version;
PyObject *name; /* reference to exactly a str or None */
PyObject *value; /* borrowed */
};
static struct
method_cache_entry method_cache[1 << MCACHE_SIZE_EXP];
the 'version' field in the entries, plus specials flags and a new
field added to the type object structure are used to determine the
validity of the cache... is not so easy to explain in words... Being
global, you can expect oscure bugs ;-), specially if you play with
tp_dict, as Cython does...
