That's because eshell special cases sudo and uses an internal command
that calls tramp behind the scenes.  The result is this:

,----
| ~ $ tty
| /dev/pts/3
| ~ $ sudo tty
| not a tty
| ~ $ /usr/bin/sudo tty
| /dev/pts/3
| ~ $ 
`----

If sudo is configured with the tty_tickets option (recommended for
security reasons), you'll have to enter the password each time.

I tried "alias sudo /usr/bin/sudo", but that worked badly.  Any eshell
guru around with better suggestions?
