Multi-threaded 'git clone'

Greetings,

Cloning huge repositories like Linux kernel takes considerable amount
of time. Is it possible to incorporate a multi-threaded simultaneous
connections functionality for cloning? To what extent do we need to
change the architecture of the current code and how large would be the
scope of the work? That just seems an interesting idea to me and would
liked to share it with the community.

Regards
