>Description:

	The /usr/local/etc/rc.d script for Apache has a "gracefulstop" and
	"gracefulrestart" option in it.  nginx has this capability via signals,
	but the rc script doesn't directly support all of it.

	The "upgrade" option more or less handles the "gracefulrestart" case.
	Here is a very simple patch for the "gracefulstop" case.

>How-To-Repeat:

	n/a
