------------------------------------

Bringing a comment from the last time that we reviewed scheduled issues:
> Last time Ross said:
> > OK to go into 0.9, but we will need a FAQ entry explaining how to turn
> > caching off for development since with it on we are forced to reboot
> > Forrest each time the LM is changed. Tim mentioned in the archives how
> > to turn it off.

> Now that we are using the locationmap extensively it is showing up just how innefficient it is. The problem is that for the majority of requests there are multiple reqeuests to the locationmap. We can make things much faster (especially on the first page request) by caching results in the locationmap.
> I think a simple cache will sufice, lets just provide a static hashmap using the hint as a key and, of course, the location as the value.
> If we test all locationmaps and find no result we should record that tere is no result in this hashmap. This will also be a good place to throw an exception so that Cocoon can better report such errors (see FOR-701)
