Frankly, this feels a bit like asking what the 9th byte in an IP
header is used for (it's TTL, but who's, uh, counting?) -- "That's why
God gave us packet analyzers" should be counted as an acceptable
answer.  If not, you'll find yourself skipping over plenty of
extremely well qualified candidates in favor of those who have crammed
recently for some sort of exam in hopes of compensating for their
short CV.
