/etc/rc.d/netwait allows a list of IP's to be specified in
$netwait_ip, and tries until $netwait_timeout (def 60) seconds pass.
The current incarnation takes each IP in turn, and tries for
$netwait_timeout seconds. This is rather unpleasant, since it means
that firstly, it can take up to $netwait_timeout * N seconds to pass
through, and secondly, if the first IP in the list isn't available,
it'll take at least _timeout seconds.
Any of the IP's should equally satisfy things; if the second (or
later) isn't sufficient, it shouldn't be in the list, and if it is,
it should be as good right off the bat as a minute (or more) later.
netwait should look over the list internally each period, and go
until the timeout hits. Attached patch makes a minimal change to get
reasonably close; it still waits a second on each IP, so the 5th IP
in the list won't get tried until 4 seconds have elapsed. If the
timeout isn't divisible by the number of IP's specified, it can go
overtime by the modulus (or by the number of IP's, if it's greater
than the timeout). I don't consider any of those showstoppers; I
have a hard time imagining cases where more than 2 or 3 IP's could be
in the list.
Possibly cosmetics of the messages may benefit from further
adjustment; I've chosen to leave that shed unbiked.
