>Mobile web apps are slow because they're secure, precisely for the reason that they cannot examine or manipulate underlying system memory. I believe the idea he was getting at was "you need to be able to tell how much memory is available to your (web) application, how much of that memory you've already used, and you need to be able to accurately predict how much memory will be allocated in the course of performing an action, in order to achieve acceptable performance on mobile," not "you need to be able to directly bang the address space." You can certainly have those features in a safe language.
