Hmm, if we allowed it, this would be a nice way to kill your Zope
server. See the docs on that:

 $ pydoc os.execv
 Help on built-in function execv in os:

 os.execv = execv(...)
     execv(path, args)

     Execute an executable path with arguments, replacing current\
     process.

            path: path of executable file
            args: tuple or list of strings


In general, you can use any Python library module you like from
"trusted" code (code written in filesystem products).  "Untrusted" code
(written PythohScripts, PageTemplates, etc.) has access only to modules
which are specifically authorized.

At a guess, by the way, the function you want is 'os.system', or better
yet one of those offered by the 'subprocess' module.
