    [ no signal delivery due to returning to kernel space, blah blah blah
    :-) ]

    For 2.4.x I'd just check for sigpending in this wait loop.

    Longer term (ie. 2.5.x and onward) we should look into ideas like those
    mentioned by Ben. I for one would not complain about seeing dhcp
    getting removed from the kernel :-)
