With 1.0.6, test.sil (Latin text) took 6.1s; a stripped-down version of
Khaled's Arefruqaa test file (30,000 lines of Arabic) took 59.1s

With HEAD, test.sil took 5.9s, Khaled's case took 60s. So no discernible
advantage.

Even removing the "obeylines" from Khaled's case and shipping the whole
lot of Arabic to the shaper at once did not show much of a speed
advantage either...
