Description Vladimir Voskresensky 2012-03-20 16:46:59 UTC 
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

Vladimir, Does the bug duplicate a bug #217776?
Comment 2 Vladimir Voskresensky 2012-12-29 10:14:55 UTC 
no. This one is about merging DeepReparsing activities related to invalidation. Not it's ofthen multiple per-file activities while better to have one batch processing
