does deleteObject() free memory?

Hi,

the following test gives 4.5 MB /tmp/db/data. Did I forget
something or doesn't deleteObject() free memory?

Thanks,

  -hh


import DE.softwarebuero.ozone.LocalDatabase;
import DE.softwarebuero.ozone.OzoneRemote;

public class NodeTest {
    private final static String dbPath = "/tmp/db";
    private final static String className = "NodeImpl";
    private final static String objectName = "root";

    public static void main (String[] args) throws Exception {
        final LocalDatabase db = new LocalDatabase();

        try {
            db.open(dbPath);
        } catch (Exception e) {
            db.create(dbPath);
            db.open(dbPath);
        }

        try {
            db.reloadClasses();

            for (int i = 0; i < 10000; ++i) {
                db.deleteObject((OzoneRemote)db.createObject(className,
objectName));
            }
        } finally {
            db.close();
        }
    }
}
