INTERNAL to EXTRA_RETAIN, because not all "internal" communicators
have this flag set (only internal communicators with CIDs less than
their parent). Hence, what this flag ''really'' means is that there
was an extra RETAIN performed on it. So name the flag just that --
EXTRA_RETAIN -- indicating that an extra RETAIN has occurred.
