VERY Slow to start up when no network

[Chanchao]

Does anyone else get this?

When no network connection is available, for example because I'm still
set to the company LAN but starting up at home to later join my home
wireless network, then the startup takes AGES.  Some things time out
causing a black screen with log messages, then finally I get to the
login screen, but then again it takes forever for everything to come up,
I even get a Gnome error message saying that stuff didn't respond and I
may not see themes, sounds or backgrounds as configured.  But it does
all come up properly eventually. Also opening applications (The Network
Control Panel!) takes forever and several tries. 

Then after I finally click off the checkbox for LAN and enable wireless
everything is fine.

Perhaps unrelated, but Evolution email also freezes up every 30-40
seconds for about 5 seconds or so when there's no network available,
also when just writing a message. The whole screen turns grey (a Compiz
thingy I think) then comes back to life only to freeze up again 40
seconds later.

I remember the good old days when just the clock NTP synchronisation
caused delay when you were sans-network.......  This however is a lot
worse.
