| - Set the process title."; 
| - 
| - static PyObject *
| - posix_setproctitle(PyObject *self, PyObject *args)
| - {
| -       return posix_1str(args, "s:setproctitle", setproctitle);
| - }
| - 
| - #endif HAVE_SETPROCTITLE

It looks to me like the only platforms that have setproctitle()
at this point are NetBSD, FreeBSD, OpenBSD and BSDI.  Most of the
rest of the UNIX world does have some way to overwrite the command
line as seen from "ps", but not all very pretty.
