I would have thought that as well, but it turned out here, that the gain
on a "normal" menu item is marginal if there is any (depending on the
speed of the db and its access of course...).

But agreed, if your menuitems are more complex and maybe contain
stdWrap-ped cObjects or the like, this might be quite useful. So
configurable (again) seems to be the answer.

Maybe we should think about what should be the default (caching or not)
- as far as I am concerned my vote goes for no MENUDATA caching by default.
