When would you call destroy? Certainly, a popup can be removed from the
map without it being destroyed: it can be re-added at a later time, and
we use that behavior in some applications here at MetaCarta.

In general, removing things is not the same as destroying them, and
depending on when they are created, you may have to clean up after
yourself rather than depending on OpenLayers to do it for you.

If you use a feature to create the popup, it destroys the popup for
you. If you create your own, you're on your own.
