killall will kill ALL your clisp processes, not only the one you want to
kill.

Given the current state of affair, your best bet is to open a pipe
between the parent process and the clisp process, and use it to provoke
a killing sigchld

You can also run lisp.exe directly.  You must be careful with the options.



Perhaps it would be a good idea to remove the call to fork() from the
clisp driver?
