Review request for Nepomuk and Vishesh Handa.


Description
-------

Possible call sequence. processNextIteration call process, queue is empty, then trigger finishIteration. But "process" itself will also trigger finishIteration in the future when KJob finished. Two finishIteration call will cause there might more than one nepomukindexer running, and it will fork more and more.
