I use dhclient (I know you said in a different message in this thread
that you don't like it), which by default does a bunch of
DHCPDISCOVERS, and if they all fail, it then goes to sleep (for 5
minutes by default), and then begins the process again when it wakes
up.  This behavior seems to be exactly what you need; unfortunately, I
don't know anything about pump.
