At least i wish i can cancel the `ping` and return control to stumpwm.

I am using stumpwm built with threaded clisp-2.49. There is a user

#'sh function as below:
(defun sh (cmd)
(let ((str (ext:run-shell-command cmd :output :stream)))
(loop for line = (read-line str nil)
until (null line)
do (print line))))
When run (sh "ping 192.168.1.1"), The stumpwm will not do anything. I
know
`ping 192.168.1.1` will not terminate unless user break it.
What is an elegant way to handle such a problem ?
As far as I know ping never quits. It just pings endlessly. So you've
written a function that reads ping's output line by line until it
quits, which it will never do. What do you want to have happen?
