Yeah, wasn't entirely sure about the location, but I want to call delete as soon as the refcount is 0 and can only reliably do that there.  locale_dtor can't count on refcount when multiple threads are used.  should I change locale__Locimp_dtor to return true if locale_dtor should call delete?

Thanks
