> UnsafeAccess.unsafeCopy should not copy more than UNSAFE_COPY_THRESHOLD on

> In *UnsafeAccess.unsafeCopy*, we calculate a _size_ __ to be read, no greater
> than UNSAFE_COPY_THRESHOLD, if total _len_ is larger than
> UNSAFE_COPY_THRESHOLD:
> {noformat}
> long size = (len > UNSAFE_COPY_THRESHOLD) ? UNSAFE_COPY_THRESHOLD : len;
> {noformat}
> But then we simply read the whole len anyway:
> {noformat}
> theUnsafe.copyMemory(src, srcAddr, dst, destAddr, len);
> {noformat}
> I believe the real intention here is to copy chunks of _size_ bytes, the
> current code is already copying everything on the first iteration, then
> performing additional chunked copies.
