You have to make sure that the duchain-objects stay valid for the time you unlock the duchain-lock, you can use IndexedDeclaration or IndexedDUContext or similar for that.

Ok, I'll rewrite that part accordingly.
BTW, I was referring to this: http://bugreports.qt.nokia.com/browse/QTBUG-10440
Which means that it should be doing the same thing as the DocumentAccess's replaceCurrentAccess function, using a BlockingQueuedConnection.
