Does anyone know how to stop Chrome doing this?

Chrome seems to group all tabs I open through the same page into one process. If I copy and paste the links individually into separate tabs, it creates new processes, but when I just middle click links, it groups them into one.

I want to force Chrome to create a new process for every tab because when one page locks up, it freezes pretty much all the tabs I have open and if one of the tabs crashes, it takes the rest with it. You can apparently alter Chrome's process model to one called "--process-per-tab" which seems to be what I'm looking for, but when I try and open Chrome with this argument via the terminal, it doesn't work. It's likely I'm not using the correct command; what I tried was:

```
/Applications/"Google Chrome.app"/Contents/MacOS/"Google Chrome" --process-per-tab

```

I'm on OS X and using the latest dev build 5.0.396.0.
