The main Apache process runs as root, and each Apache child process
runs as a less-privileged user, and so would not have permission to
signal the main process to tell it to reload.

You could use a conventional perl script (ie not mod_perl) which is
setuid root (though you'd need to be extraordinarily careful), or have
an external daemon running as root which accepted restart requests on
a UNIX socket, then have your script send these requests.

Scripts such as perl or ksh do not become root with setuid.
They really do not get the same privilege. Setuid to root
works ok with a compiled executable.
