afaik the problem is getting *all* uses to make the renaming correctly. 
And for that *all* project files are checked to be up2date. And this 
takes time. Long time.

The thing with "private to file" stuff is that the current mechanism 
(afaik) does not check that. It does not know which file accesses a 
private/protected/public member of a class for example.

Anyways, David will know more.
