In the createCollection coordinator we accidentally copy all chunks after we serialize them. To avoid this copy we could simply use move semantic.
While in versions 6.0+ this is not particularly problematic because we usually do not have a huge number of chunks, in previous versions (<= 5.0) the number of chunks could be very high, on the order of millions.
