<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Hmm, what happens if the timer times out, but there are still queued lines in the thread? i.e. the thread is currently working on some lines when its event loop is being exited. Since the event-queue is local in QThread::run() (IIRC) all the still-queued things would be lost in this case.
So I guess whats needed here is for the outputmodel to keep track of how many lines that where sent to the thread have been finished and if all are done, then start the timer to shut down the thread.</pre>

Fixes performance issues in the OutputView tool view when inserting (and filtering) a large number of lines.
As discussed in IRC.
The patch consists of 6 commits which were pulled from the wip/filter_output_threaded branch.</pre>
