Well, it would be nice if that bug were fixed...  But it doesn't answer
the question of why, when I come back up, do I get a new IP Address from
DHCP?  It's almost as if NM/dhclient don't know that it can just make
a DHCP_REQUEST and instead always falls back to a DHCP_DISCOVER.  This
is true even if the Network Name (ESSID) hasn't changed!  *THIS* I consider
a bug in NM.
