It almost sounds like ARP is being slow. I do not think that is it though.

AFAICT, it's not running:

I waited a couple of minutes after typing the first "net view" command
in Windows before re-running "arp -a". Samba's IP is still listed,
but
"net view" is again slow. Like Windows/Samba only keeps an open 
connection for a few minutes before closing it or something.
