  Dash: very high latency responding to input

Bug description:
  After an upgrade to Ubuntu 11.10 the Dash now has very high latency
  (500+ milliseconds) responding to user input, such as typing
  characters in the Dash search and seeing those letters displayed.

  The GNOME HIG requires an input/feedback latency of below 100
  milliseconds.

  If the update is waiting on results/matches to appear it should be
  possible to focus on displaying the user input initially, and then
  waiting for further results to come in.

  (In order to always meet the 100 millisecond target, it may be
  necessary to find ways to transparently degrade the visual quality).
