 ### The `--zero-fill-buffers` command line option
 
 Node.js can be started using the `--zero-fill-buffers` command line option to
-force all newly allocated `Buffer` and `SlowBuffer` instances created using
-either `new Buffer(size)`, `Buffer.allocUnsafe(size)`,
-`Buffer.allocUnsafeSlow(size)` or `new SlowBuffer(size)` to be *automatically
-zero-filled* upon creation. Use of this flag *changes the default behavior* of
-these methods and *can have a significant impact* on performance. Use of the
-`--zero-fill-buffers` option is recommended only when absolutely necessary to
-enforce that newly allocated `Buffer` instances cannot contain potentially
-sensitive data.
