<div class="im">FWIW, JRuby originally had a stable Array#sort, but because it was</div>
slower than MRI&#39;s unstable sort (and we got bug reports to that<br>
effect) we replaced it with an unstable hybrid sort based on<br>
quicksort. Shortly after we did that, someone raised an issue against<br>
MRI to get it to move to a stable sort :)<br>
<br>
As far as I know, MRI hasn&#39;t changed yet.<br>
