L4 and L5 are only stable if the mass ratio of the two primary bodies
is large enough.  I'd have to do some figgurin' to reconstruct the
limiting ratio, but as I remember, the Earth is just barely large
enough to make the Earth-Moon L4 and L5 stable.  A corollary is that
the hotdog-shaped stable regions around the Earth-Moon Trojan points
aren't very large or `deep'.
