Review done. In words/part/tests/TestDocumentLayout.cpp before 21 tests failed 
and now 25 are failing. The probably most interesting one seems to be in 
placeAnchoredFrame3() which does;

QTextLayout *lay = doc->begin().layout();
QVERIFY(lay->lineCount() >= 2);

Before the refactoring that lay->lineCount() call returns 17 here and after it 
returns 1. Also waiting for a few seconds after the layout doesn't change that 
result either. Can that be a problem?

Beside this case it looks fine to me :-)
