Anthony,
Can you have a look at this report ? My guess is that the problem is
due to ifdown's behaviour. But maybe it is rather bad coordination
between ifupdown and updhc ?
Thanks.

I'm not sure whether this is a problem of udhcpc and/or resolvconf
and/or ifupdown.
Apparently not resolvconf:
samples[0]# ls /etc/resolvconf/run/interface/
samples[0]# udhcpc -i eth0
udhcpc (v0.9.9-pre) started
Sending discover...
Sending select for 10.64.251.123...
Lease of 10.64.251.123 obtained, lease time 3600
Resetting default routes
adding dns 194.179.1.100
adding dns 194.179.1.101
samples[0]# ls /etc/resolvconf/run/interface/
eth0.udhcpc
samples[0]# resolvconf -d eth0.udhcpc
samples[0]# ls /etc/resolvconf/run/interface/
samples[0]#
So apparently, resolvconf does its job.
udhcpc looks ok too:
samples[0]# ls /etc/resolvconf/run/interface/
samples[0]# udhcpc -i eth0
udhcpc (v0.9.9-pre) started
Sending discover...
Sending select for 10.64.251.123...
Lease of 10.64.251.123 obtained, lease time 3600
Resetting default routes
adding dns 194.179.1.100
adding dns 194.179.1.101
samples[0]# ls /etc/resolvconf/run/interface/
eth0.udhcpc
samples[0]# killall -SIGUSR2 udhcpc
samples[0]# ls /etc/resolvconf/run/interface/
samples[0]#
Now simply killing udhcpc leaves a dangling file:
samples[0]# udhcpc -i eth0
udhcpc (v0.9.9-pre) started
Sending discover...
Sending select for 10.64.251.123...
Lease of 10.64.251.123 obtained, lease time 3600
Resetting default routes
adding dns 194.179.1.100
adding dns 194.179.1.101
samples[0]# ls /etc/resolvconf/run/interface/
eth0.udhcpc
samples[0]# killall udhcpc
samples[0]# ls /etc/resolvconf/run/interface/
eth0.udhcpc
My guess is that ifdown just kills udhcpc without deconfiguring the
interface.
