Basically the problem is this. Whenever an intensive application runs which consumes lots of memory or hard drive i/o, Ubuntu (maybe this is more general to any Linux distro, I don't know) freezes completely. It is even impossible to kill the offending task. Only "solution" is then to wait for the application to finish, or restart PC. The links above give specific examples of what to do to reproduce this issue. I have used Windows in the past (hate to compare, and I'm not coming back to it), and I know it doesn't have this issue (at least not as bad as Ubuntu), in the sense that the PC is always somewhat responsive, and you can attempt to kill the intensive application to recover the system. So I guess this is something that can be fixed.
