Both cable and wifi active, not a bug?

It sounds like a feature to me - provided it handles it well.  That is, I
can envision situations where I can have both enabled, and even make use of
both; but I have also had situations where both were accessible, but the
DHCP server on one network wasn't. I really don't want it to set up my
network with the default gateway on that interface - because the odds are I
can't actually get anywhere on it.  I would hope it sets the default
gateway to (1) only a network that actually promises one via dhcp and (2)
on the _faster_ connection if both offer a gateway.
