// verrry simple way to keep single sets of data for all kinds of purposes.
//
// the trick is: if you put these mappings here, they only exist once in
// the entire system, whereas if defined in your application they will be
// recreated for each instance of your app.
//
// net/d/share was essentially a similar idea, but this works better in library.
// use something like this to access the mappings:
//
// volatile mapping mood2jabber;
// mood2jabber = shared_memory("mood2jabber");
