[ale] Sleeping Beauty

ALErs -

I started a 'df' that hung, and now reports its state as follows:

[jmm4450 at swlab01 jmm4450]$ ps 26609
  PID TTY      STAT   TIME COMMAND
26609 ?        D      0:00 df

'man ps' identifies 'D' as "uninteruptible sleep" and this sure seems to be
the case: I've killed everything I can associate with this task, including
the window server under which it was started, but ol' 26609 just hangs in
there!

Any way to kill this #$%@%^~~!!?

TIA.
