James> referencing the string object.I'm skeptical about performance as well, but not for that reason. A string object can have a referent field. If not NULL, it refers to another string object which is INCREFed in the usual way. At string deallocation, if the referent is not NULL, the referent is DECREFed. If the referent is NULL, ob_sval is freed.
