>Description:
	The patch in the Fix: section uses setproctitle() to set the
	display-name for WSGI children.

	e.g. in httpd.conf:
	WSGIDaemonProcess moin display-name=wsgi-moin

	pstree output becomes:
	 |-+= 06591 root /usr/local/sbin/httpd
	 | |--- 06592 www httpd: wsgi-moin (httpd)
	 | |--- 06593 www httpd: wsgi-moin (httpd)
	 | |--- 06594 www /usr/local/sbin/httpd
	 | |--- 06595 www /usr/local/sbin/httpd
	 | \--- 06596 www /usr/local/sbin/httpd

	CC'd port maintainer.

>How-To-Repeat:
	Set a display-name in httpd.conf
