It should be right. It would be very easy for a bucket to be based on a pipe
or a socket, thus being uncopyable, but it knows the length of data to be
read from that pipe/socket.
Imagine if you have a particular protocol running over some socket to a
backend server. You know the next chunk of data is 1000 bytes. You insert
your custom socket bucket, saying "<this> socket, 1000 bytes". It can be
read, but it can't be copied.
