DeepReparsing utils invalidate big set of related files on each file change event. It results in log cpu load activity, especially during clean&build or vcs activity from command line on systems with native file listeners where iconified NB receives file events.
Code Model should coalesce add/remove events as change events and try to do delayed but merged file change handling on set of added/removed/changed files to reduce number of DeepReparsing activities from N to 1 where N is number of affected files. It will reduce number of forced parsing activities from N to 1 as well
