Vulnerability Development: RE: Problem with xkill

[Joe Gruppuso <agruppus () jcals army mil>]

This was merely a controlled experiment; I was curious at to what it
would do (In otherwards, I asked for the ability to be able to access
the remote display.)  This brought forth realization that xkill, in
application, behaves nothing like kill.  Thank you all for the input, it
was most helpful.

Obviously not, as you could connect to another display.

I'm not sure what you call "graphical kill", but once the connection tp
the X server is cut, there is nothing than the client can do, apart
from saving its data and exiting nicely.
Most client just die on SIGPIPE.
