Hi Markus:

This does help.  I have an example that takes 9s with ess-eval-visibly-p 
set to t without your change; and with your change it
is 4s.  However, with ess-eval-visibly-p set to nil it is
practically instantaneous; this example is only 30 lines and
requires no computation whatsoever, so 4s is still too much.
So, there must still be a bug somewhere, but this fix definitely helps. 
  Checked in; will appear in ESS 5.9 RSN.
