Python string comparisons can't be using anything that relies on nul-termination, because Python strings can contain embedded nuls. Possibly it uses memcmp(), but that takes a length. You have a point when it comes to passing strings to other C routines, though. For those that don't have a variant which takes a maximum length, the substring type might have to keep a cached nul-terminated copy created on demand. Then the copying overhead would only be incurred if you did happen to pass a substring to such a routine.
