Forgive me for not having time to go read the dhclient details, but
unfortunately I'm a bit pressed for time this morning.  I just wanted to
confirm that dhclient gives a "first reasonable try" if the link is up in
this situation, rather than immediately backgrounding, since some services
will behave poorly if they don't find IP addresses, etc.  Ie., this
operates like the NFS mount background option: "If at first you don't
succeed, try again on your *own* time". 

The services I have in mind are, indeed, network file system mounting,
sandboxed named, sendmail, and third party applications that like to bind
each IP address manually rather than use INADDR_ANY.
