* Without any firm definition of *what* we are talking about,
  I think placing blame is a bit silly.

* Modern toolkits in my experience make far less roundtrips 
  than older toolkits like, say, Motif. I don't think "too
  many roundtrips" is the answer. Modern toolkits are slower
  than old toolkits, and they *should* be slower than old
  toolkits because they do vastly more.
  
  Not that us toolkit writers can't make things better, and
  shouldn't be trying hard to do it, but the above point of 
  view is entirely too simplistic.

* To put my first point a slightly different way, you can't 
  optimize until you can measure what you are trying to
  optimize.
