Found it!  
Domain login in 8 seconds!!!
One must enable "Do not detect slow network connections".  The method it
uses to do that is to PING the server.  Not poke at one of the server
ports which should be open on the firewall, mind you, but do a regular
ICMP ping, which is of course blocked on 99.99% of all linux servers. 

The W7 client is currently set as follows;

1.  hosts entry for the samba server (probably not important)
2.  Do net detect slow network connections.  (Eliminates the 15s gap).
3.  Set max wait time for the network if the user has ... (Eliminates
the 30s gap)
4.  Do not check for user ownership of roaming profiles (possibly not
relevant).

Thanks to everybody who helped with this!
