Hello, I am in search of most efficient way to convert Buffer to
ArrayBuffer.
Can somebody explain this paragraph:
"A Buffer object can also be used with typed arrays. The buffer object is
cloned to an ArrayBuffer that is used as the backing store for the typed
array. The memory of the buffer and the ArrayBuffer is not shared."

from http://nodejs.org/api/buffer.html

for me this means that I can do

var ab = new Uint32Array(new Buffer(16));

and get
ab.length == 4;

but this is not so
ab.length is 16

is it a bug? or I get that paragraph wrong?
