- As written in another thread if you can get parallel graphics conversions
  for document load and export, that would be cool.

- Another slow thing is document comparison. But how much of it can be parallel
  I don't know. And even before that we should first make it correct (nested 
  insets are not handled correctly), nice (unnecessarily spilled-over characters)
  and sequentially fast (word-based instead of character-based).

- Advanced search over lengthy math-loaded documents is slow. But again, 
  before going parallel one should check the unnecessary bottlenecks in
  sequential space...
