just to make sure, how does 'top' output of the l + "lt 3" testcase look
like now on your laptop? Yesterday it was this:
4544 roman 20 0 1796 520 432 S 32.1 0.4 0:21.08 lt
4545 roman 20 0 1796 344 256 R 32.1 0.3 0:21.07 lt
4546 roman 20 0 1796 344 256 R 31.7 0.3 0:21.07 lt
4547 roman 20 0 1532 272 216 R 3.3 0.2 0:01.94 l
and i'm still wondering how that output was possible.
