(lack of) security of client workstations

   Who says your abort sequence has to be L1-A? Read man 5 kbd. I
   haven't tried it, but TFM indicates that the two key sequence can
   be changed.  It would take an awful lot of pounding to discover the
   new sequence.

It would only take one pair of quick eyes watching an operator in a public
lab fix one machine.  Security through obscurity is no security,
particularly when it's not all that obscure.
