// waba: Watching for updates is disabled for now because even with FAM it causes too
// much problems. See BR68220, BR77854, BR77846, BR79512 and BR85802
// There are 3 problems:
// 1) addDir() keeps looping on recursive symlinks
// 2) addDir() scans all subdirectories, so it basically does the same as the process that
// is started by KQuery but in-process, undoing the advantages of using a seperate find process
// A solution could be to let KQuery emit all the directories it has searched in.
// Either way, putting dirwatchers on a whole file system is probably just too much.
// 3) FAM has a tendency to deadlock with so many files (See BR77854) This has hopefully
// been fixed in KDirWatch, but that has not yet been confirmed.
