File::ChangeNotify::Watcher::Default - Fallback default watcher subclass
This class implements watching by comparing two snapshots of the filesystem tree. It if inefficient and dumb, and so it is the subclass of last resort.
Its $watcher->wait_for_events() method sleeps between comparisons of the filesystem snapshot it takes.
