CkSectionID *	sec_id
	An unused, and probably unnecessary array that was used to avoid a memory corruption that clobbers members in this class. The bug has likely been fixed.
CkSectionID *	copy_of_sec_id
	Saves a copy of the CkSectionID sec_id when enqueing a multicast message.
CkArrayID	array_id
CmhMessageType	type
	Type of message we are buffering.
