Does this support all features of KDirWatch? Last time I checked
QFSWatcher had some limitations.

And if it supports all features, I think KDirWatch could simply drop its
kqueue and inotify implementations and use QFSWatcher for that as well.
Which would mean using QFSWatcher as default on Win32 and wherever
kqueue is used (I think BSD) and using FAM on linux or falling back to
QFSWatcher if fam doesn't work/is not installed.
