The first thing I did on getting dwm was to add a (badly named)
function:

void
startwm(const char *arg) {
        static char *shell = NULL;

        if(!shell && !(shell = getenv("SHELL")))
                shell = "/bin/sh";
        if(!arg)
                return;
        execlp(shell, shell, "-c", arg, (char *)NULL);
        fprintf(stderr, "dwm: execlp '%s -c %s'", shell, arg);
}

and then add a keybinding, Mod-q, in config.h keys[] to re-exec the process:

        { MODKEY, XK_q, startwm, "exec dwm < /dev/null" },

I called it `startwm' because I wanted to exec other window managers
too. but it is really just an exec(2) and spawn doesn't cut it here.

PS Perhaps this could be folded into, or perhaps spawn() could be
layered on top of a different function which could also be used for this
purpose?
