Two reasons. First, there aren't enough low ports in cases where
applications make large numbers of outgoing TCP connections like web
crawlers do. Second, there tend to be a lot of quasi-reserved ports
below 32,768 (such as 6666, 7000, 8000, 8080, and many others) and it
could cause some inconvenience if these ports were used accidentally.
