>
> The index into the circular buffer is computed by taking an absolute counter
> modulo the buffer size. When the absolute counter wraps around, there will be
> a jump in the computed indexes if the buffer size is not a power of two. This
> can cause garbage to be copied into the buffer or written onto the wire. The
> constructor should round the requested buffer size up to the nearest power of
> two.
