My bug report contained two scenarios to produce sluggish response and
high CPU utilization.  These scenarios were

  (1) move point to the end of buffer, and start typing

  (2) Put point in line 1, column zero; press and hold the down (then up)
  arrows to move point down (then up) the org-mode buffer.

Setting bidi-paragraph-direction: left-to-right eliminates the problem
with scenario (1).  However, it has no effect on scenario (2).
