It was worth a try:
        PeeCee: {35} umount -f 140.165.31.92:/disk9/dkelly
        umount: /disk9: Device busy
        PeeCee: {36} umount -f 140.165.31.92:/disk9
        umount: 140.165.31.92:/disk9: not currently mounted
        PeeCee: {37} df
        ^C
        PeeCee: {38} ls /disk9
        ^C
        PeeCee: {39} w

        USER     TTY FROM              LOGIN@  IDLE WHAT
        dkelly   p0  PowerMac          1:41PM    11 df
        dkelly   p1  PowerMac          1:41PM     - w
        PeeCee: {40}

Not sure how long that "df" will block until it gives up. Did I forget to
mention this is 2.1R running the shipping GENERIC kernel?
