Then it shouldn't be triggered for allow-hotplug interfaces.

ifupdown supports link detection, as you can see in
/etc/init.d/networking (the following function ifup_hotplug
applies to allow-hotplug interfaces in /etc/network/interfaces):
ifup_hotplug () {
if [ -d /sys/class/net ]
then
ifaces=$(for iface in $(ifquery --list --allow=hotplug)
do
link=${iface##:*}
link=${link##.*}
if [ -e "/sys/class/net/$link" ]
then
# link detection does not work unless
we up the link
ip link set "$iface" up || true
if [ "$(cat
/sys/class/net/$link/operstate)" = up ]
then
echo "$iface"
fi
fi
done)
if [ -n "$ifaces" ]
then
ifup $ifaces "$@" || true
fi
fi
}
And this works.

No, according to the logs, /etc/init.d/networking does not block boot.
