Yes, the fact linux mm currently sucks. How else would you explain possibility of killing random (often root owned) processes using a 5 lines program started by an ordinary user? Killed process could be an apache web server or X server on a desktop. I demonstrated this flaw few months ago here and only Kame tried to find a way to fix it but encountered noncooperation. I don't know what to say, really. Sad... Actually funny, when you know that competition OS, often ridiculed by linux users, doesn't suffer any consequences when that same 5 line program is run.
