Comment 607 for bug 620074

In think in my case we have a system hang for two reasons. I don `t know that there does Opera, but it looks like that video card output is also limited, and when any application tries to send too much data to transfer GUI starts feeling less refreshed from this hangs. Despite the fact that htop does not show any CPU utilization or waiting for i/o. The second case is more traditional, it is to hang when accessing memory (memory of 2GB) htop shows us that even 2GB swap allocated. And then the freezing occurs because of the waiting of the hard disk. That's OK, but bad that affects all applications, even those to whom the available memory would be enough. The worst thing is that there is affects as a whole system responsiveness and GUI. I want to help fix these problems, write what I can do for this.
