What I was wondering too, and why I somehow believe that suspending  
line-breaking and starting the page-breaking phase earlier is likely  
to be 'easier' to implement (even though the required changes would  
impact a lot more classes). It would basically come down to extending  
the approach that is currently taken when dealing with span-changes or  
forced page- or column-breaks: exit the line-breaking loop, start page-
breaking for the element-list up to that point, and return later to  
continue with the line-breaking. Currently, this approach always uses  
separate PageBreakingAlgorithm instances, but I don't think it would  
be very hard to re-use the same PBA and append the new elements to its  
'current paragraph'.
