The copy operation is done, because in case the next element alters the data
that buffer contains. If it then requests same buffer again, it gets the
original data.
Are there any specific rule in this case, can element alter the buffer data and
then request resending the buffer? If not, then it's quite small change to drop
the copy operation from the queue patch.

For our understanding, this is the case. But let's hear Wim's comments.
