I really thing we are too close from the release to implement it now. I
prefer a well tested sub-optimal implementation rather than a ultra-
optimized buggy implementation that gets loaded in all Xfce components
because it's part of one of the base libraries... (I'm am not saying
that you implementation is buggy, but if it's too recent, it's not
tested enough for a final release)

So we can live with the big hash table for now, we'll see later for
improving things in 4.4
