JDK 1.3 java.awt.MediaTracker.waitForAll() does not close image files which
causes a leak in file descriptors.

A test example which demonstrates this problem.
===== test.java ========
import java.net.*;
import java.awt.*;

public class test1 {
    public static void main (String argv[]) {
            Component comp = new Canvas();
            MediaTracker tracker = new MediaTracker(comp);
            Image image = null;

            try {
                image = Toolkit.getDefaultToolkit().getImage(new URL("file:/tmp/im0.gif"));
            } catch (MalformedURLException mue) {
                System.out.println(" failed: Unexpected " + mue);
            }

            try {
                 tracker.addImage(image, 0);
try {
tracker.waitForAll();
                 } catch (InterruptedException ie) {
                     System.out.println(" failed: Unexpected " + ie);
                     return;
}
                tracker.removeImage(image, 0);
          } finally {
            image.flush();
            System.out.println("QUIT");
            System.exit(0);
          }
    }

}

In the example above the following file "/tmp/im0.gif" wouldn't be closed directly after it was read. In this example the file would be closed only
by the system _exit() call when VM dies. (Analyse requests to the OS system
