Again, a long since solved problem in the context of the current 
discussion, as when package A is uninstalled, the PM verifies files 
against the package database entry for that package, and doesn't remove 
changed files.  Otherwise the normal upgrade procedure of installing the 
new then uninstalling the old wouldn't work.
