Well, I've identified a workaround, not really a fix.  And it's really
just disabling ipv6.  I'm not convinced my nameservers are the problem,
rather I think there's something broken with Fedora 11's use of ipv6,
or possibly the linux kernel post 2.6.27.

Added to /etc/modprobe.d/aliases.conf: (new file I created)
install net-pf-10 /bin/true
install ipv6 /bin/true

Added to /etc/modprobe.d/blacklist.conf:
# ipv6 die die die
blacklist ipv6

symptoms have completely cleared up, and I don't use ipv6, so I'm
happy.

Thank you for your assistance and patience in troubleshooting what
turned out to be not your problem.

-Brian
