According to http://www.masteringemacs.org/articles/2013/12/29/whats-new-in-emacs-24-4/ (see section File handling changes) the upcoming version of Emacs will support file notifications via inotify or glib. Since inotify is not supported by FreeBSD, does glib wraps kqueue(9) and therefore can Emacs take advantage of file notifications also on FreebSD?
