<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This will cause deadlocks (see the comment at the top of foregroundlock.h), because the duchain-lock is held.
Qt-4.8 won't help too, as it will cause the same deadlock.
You can use the ForegroundLock to get the required information, but you have to move the code out of the context where the duchain-lock is held. 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.
As you have to access the foreground synchronously anyway, you don't need to change DocumentAccess. You can simply do "PersistentMovingRange r = context->createMovingRange(); unlock duchain; ForegroundLock lock; text = r->text();" to get the text</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">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.</pre>
