Daniel@0 40 /* Note that there is a subtle problem which affects
Daniel@0 41 * the use of the figure//3 HTML component: the first argument
Daniel@0 42 * is a module-qualified goal, and gets tagged with the name
Daniel@0 43 * of the module created to run the current pengine query.
Daniel@0 44 * The component results in an HTML IMAGE element whos
Daniel@0 45 * URL encodes the goal and its module. If the pengine query
Daniel@0 46 * has terminated by the time the image URL is dereferenced,
Daniel@0 47 * the call fails. Thus, to make this work with write_html/1
Daniel@0 48 * you need either a delay (eg sleep(3)) after the call, to allow
Daniel@0 49 * the image to render before the query terminates, or you need
Daniel@0 50 * to introduce some nondeterminism so that the query remains
Daniel@0 51 * active. To make it work with html term rendering, only the
Daniel@0 52 * non-determinism method will work. To do this, you can add the
Daniel@0 53 * following hold as a final goal - it succeeds but leaves a choice point.
