Keep in mind that with Hg, the whole repository is being cloned to your computer - all active (and inactive) branches, all history, etc. The up-side is that after this initial clone, subsequent pulls are pretty quick and all other operations are local and super fast (log, blame, etc.)

To further clarify what Eli said, "the whole repo" gets put into that .hg directory first, and only at the end is a working directory checkout done. So all you will see is cpython/.hg until the very last moment when it will start telling about the checkout being done.
