Yes, I know. I just needed to start with something "solid". If running at the lowest performances is stable, it gives me a reference. I had time to test another commit in the branch, but since I'm not at home, I can't say if all the commits you had identified are in. I'll probably continue tonight. -- You are receiving this mail because: You are the assignee for the bug. --1384441569.eBfbCaBE2.32490 Date: Thu, 14 Nov 2013 15:06:09 +0000 MIME-Version: 1.0 Content-Type: text/html; charset="UTF-8"

Yes, I know. I just needed to start with something "solid". If running at the
lowest performances is stable, it gives me a reference. I had time to test
another commit in the branch, but since I'm not at home, I can't say if all the
commits you had identified are in. I'll probably continue tonight.
