[issue16398] deque.rotate() could be much faster

[Raymond Hettinger]

Raymond Hettinger added the comment:

John, that wouldn't work because the blocks are fixed length and the endmost blocks are typically only partially filled, so all the data elements have to shift positions within their blocks.

----------
resolution:  -> fixed
status: open -> closed
