        <br>

        OpenLayers.Map has three functions that look like being used for

        freeing memory:<br>

        destroy(), unloadDestroy(), updateSizeDestroy().<br>

        <br>

        Am I supposed to explicitly call them or not? From the <a

href="http://dev.openlayers.org/docs/files/OpenLayers/Map-js.html#OpenLayers.Map.unloadDestroy">description

          of "unloadDestroy"</a>, for example, it seems that it is

        already called by something.<br>

        <br>

        I'm looking something similar to Google Maps' <a

href="http://code.google.com/intl/lv/apis/maps/documentation/javascript/v2/reference.html#GUnload">GUnload</a>,

        which is supposed to be run upon page unload event - is there

        something similar needed for OpenLayers?<br>

        <br>

        Thanks!</font></font>
