    kqueue: Only fallback to polling on /media and /run/media
    
    The check in _ke_is_excluded, which causes GKqueueFileMonitor to
    fallback to GPollFileMonitor when it returns TRUE, was made to prevent
    file monitor from blocking unmount of removable drives on systems not
    supporting O_EVTONLY flag in open. However, since g_mount_can_unmount
    always returns TRUE on Unix-like platforms, the check always returns
    TRUE on non-standard mount points, which is very likely to cause all
    programs on the desktop to use the polling fallback if GNOME is
    installed in a different prefix for development. This makes the desktop
    sluggish and results in bad developer experience on *BSD.
