ArrayBuffer, Int8Array, Uint8Array, Int16Array, Uint16Array, Int32Array, Uint32Array, Float32Array, Float64Array
I tested many configuration under valgrind, to find all possible errors.
It seems other browsers don't set a limit, so you can eat all memory with these arrays (danger), so khtml/kjs also doesn't set a limit. If you feel like we really need one, please tell.</pre>
