<p>Ah, you are right, now that I look at the code, this code is the most recent push (so <a href="https://github.com/mlpack/mlpack/commit/3af80c339a7a846bb3bdf305131c87eaa939fc01" class="commit-link"><tt>3af80c3</tt></a>).</p>

<p>I think your description is right, for why parallelizing <code>ReturnIndicesFromTables</code> isn't working well.  If you'd like me to run the same simulations for a previous commit, let me know and I can do that too; it doesn't take too long.  Otherwise, if you're happy with the approach here, I can start making some final comments and we can merge it.</p>
