I'd have done it the same way you did. Did you figure out what the problem
was? Did you delete the 127... line from /etc/hosts or mess up
/etc/nsswitch.conf?

If I were in a position where rebooting was absolute last resort, I'd
probably try and figure out how name resolution was being done and then find
some way to make it work the way sudo wanted.

Maybe I'd try and unplug the ethernet cable to see if that affects anything.
Too bad the system's fixed now. :-)
