Though there's a chance for khtml to know the size of the principal document, 
there's no possibility to know the size of the descendant elements before 
they have been parsed and queried.

Well, the progress bar is just a hint, and it jumps around wildly as new 
descendants become known. While it is impossible to predict the total size of 
a document at the beginning, you possibly *could* predict the total size 
after you've parsed the principal and all descendants recursively.

However, as soon as one get/post-operation doesn't deliver a content-size 
header, you're lost.
