Hi,
this could be worked around by setting e.g for eth1:

#allow-hotplug eth1 
iface eth1 inet manual
        pre-up /sbin/ip link set $IFACE up
      up /sbin/dhclient -nw -4 -v -i -pf /run/dhclient.$IFACE.pid -lf /var/lib/dhcp/dhclient.$IFACE.leases -I -df /var/lib/dhclient6.$IFACE.leases $IFACE
        pre-down /sbin/dhclient -r -4 -v -i -pf /run/dhclient.$IFACE.pid -lf /var/lib/dhcp/dhclient.$IFACE.leases -I -df /var/lib/dhclient6.$IFACE.leases $IFACE
      down /sbin/ip link set $IFACE down

That way network setup will go on without waiting for timeout.

Ciao,
Tito
