The Danish government had a program developer in the 90' for the job centers (the job centers are suppose to help unemployed people return to the job marked, they're just very good at it). Somewhere in the specs. the was a limit on how long the loading time for a window could be.

To get around this load time restriction the developer simply put less information and features into window. So rather than spending 10 seconds loading one large form and fill it out, users would have to click though X number of windows, filling out part of the form in window.

I'm not sure where I'm going with this, but your comment reminded me of this case.
