There’s been tons of reviews on chrome, literaly minutes from its release and the news was full. One thing I noticed that I didn’t see anyone talking is the several chrome processes simultaneously running.
I also did some testing using process explorer, and found that the parent process also seems to be responsible for a tab. If that tab hangs and you kill it, then all of child processes responsible for the rest of the tabs will die as well.
I haven’t seen programs designed to run under windows and using a multiprocess model to enhance its stability before. I didn’t look in the source code, but it seems that there’s a lot of consideration taken in its design process.
