for ~4 yrs or so there's been possible problems with as-paths longer
than ~50 (I think, i can't recall the exact vendor bug)
so, folk should have already been denying announcements with longer
than ~soemthing-like-45 asn in the path.. right? :)

(yes, any prepend past ~10 is arguably not worth the time)
