Spinning up instances takes a while, so I do them in parallel to save time.  I'm running CCL eval servers on the instances, so I essentially have a Lisp supercomputer that I can spin up whenever I need it.  It's pretty wizzy, if I do say so myself :-)

But there is a CL run-shell-command.  It's called RUN-PROGRAM.

And you can call #_fork through the FFI (though I'm not clear why you would want to).
