Depends. It is a configure switch for kdelibs. 
It uses:
- fam/gamin: if it was enabled and it is present
- kernel (inotify, maybe dnotify)
- polling

What does the Qt class use if not the ones above?

KDirWatch::removeFile and KDirWatch::addFile works for me just fine in 
KDE3.

Probably because it works for most cases and there was no need to change 
it.
