That's merely a transient situation caused by the LTP swapfile tests. Ordinarily, my test machine does not have swap. At the time the OOMs occur there is no swapspace and the msgctl9 or msgctl11 tests are usually being run. > The following patch should improve on that. I can give it a spin when I get home later.
