Patch 7.4.040
Problem:    Valgrind error on exit when a script-local variable holds a
	    reference to the scope of another script.
Solution:   First clear all variables, then free the scopes. (ZyX)
Files:	    src/eval.c

    A KNIGHT rides into shot and hacks him to the ground.  He rides off.
    We stay for a moment on the glade.  A MIDDLE-AGED LADY in a C. & A.
    twin-set emerges from the trees and looks in horror at the body of her
    HUSBAND.
