In its early days, rb used FAM for watched dirs.  This is on the TODO I
believe and I don't see why we can't use it for the library stating.  It
was abandoned early b/c of gnome-vfs-FAM bugs, but I think they have
been fixed.

Better to dump the overhead to an app already doing the work than to try
and do it ourselves I think.
