patch prevent IDE to burn CPU on broken symlinks.

   The author of the masterfs module did not know that the file.exists() 
returns false for a broken link.
   There is FileChangedManager and that's the biggest problem, there is a 
cached condition of file existence. `FileChangedManager.exists() and 
FileChangedManager.impeachExistence()`
   
   The code is terribly complex and the analysis is for a few days. 
   And I feel that direct reading of the file states takes less cpu time as the 
monster..
   
   And the biggest problem is my Google translator English..
