df hangs for a long time if your NFS server goes away

[Ian! D. Allen [CGL]]

If you forget the "-n" option on "df", you're stuck for a long, long time.
It seems you have to push your interrupt key, wait for a file system to
time out, then push it again for the next file system, etc.  If you have
ten things mounted from the same server, the fight isn't worth it -- you
may as well log out and log back in.

Couldn't "df" notice the *first* interrupt?  Most annoying.
