NAME
	pass - alert the exit that somebody passed through

PROTOTYPE
	void pass(object passed_through)

CALLED BY
	Anybody

DESCRIPTION
	This function is useless unless you override it.  You should secure
	it to COMMON() and SYSTEM() callers so that you don't get spoofed
	by another caller.  The function tells you that somebody
	successfully passed through, and the exit should respond.  The
	passed_through object is generally the body of a mobile.

	The default implementation does nothing.

	This function isn't access-protected.  You should access-protect
	your version of this and all other inherited functions, including
	upgraded() and destructed().

RETURN VALUE
	None.

ERRORS
	Usually none.
