Sure! How about

struct txn_terms {
	latch		lock;
	vclock_t	map;
	uint64_t	map_max;
};

struct txn_limbo {
	...
	struct txn_terms terms;
	...
};

I don't mind for any name (except "set" because
set can't contain duplicated elements and our
vclock can have same term installed for different
replicas)
