I tried logging in via GNOME, but I saw no such message.  KDE also
doesn't give a message.

I just added the real hostname, so that now my /etc/hosts file has two lines:
127.0.0.1       localhost.localdomain   localhost
the_real_ip_address   fully_qualified_machine_name      machine_name

Nothing really changed.  So I tried running the prelinker as suggested in:
http://www.redhat.com/archives/fedora-list/2004-January/msg05131.html

That also didn't seem to immediately help.  But after about two minutes 
everything started launching much more quickly (terminals in under a
second, mozilla in less than two, etc...)!!

Now, I just have to figure out why ssh is so slow.  I had first attributed it 
to the same source as the above problem, but now that that is fixed, it is
still taking a long time to connect to other machines.

Thanks (especially to D. Norris and P. Macedo)
