In my case, I don't have any forwarders set.  I see little point in
running my own name server (which I began doing because of my ISP's
crappy ones), if I simply get it to forward request to the ISP's crappy
servers, instead of acting *as* a DNS server.  :-\

Though individual applications get the system to resolve addresses for
them, they don't read the /etc/resolv.conf file and then run their own
DNS resolving routines on the DNS server addresses that they find listed
in there.  With an exception or two (e.g. Squid generally resolves
addresses on its lonesome).

I'd noticed that Windows does seem to carry on using whichever
nameserver last answered, before switching over to the other if there
was a problem.  Then, if that happens, it keeps on using the last one
that responded.  I wondered if Linux played the same trick.

Neither OS appears to use both of them all the time (spreading the
load), which I can think of as another way to make good use of having
several name servers at your disposal.

(Currently running FC4, in case that's important to the thread)

Don't send private replies to my address, the mailbox is ignored.
I read messages from the public lists.
