The repo fetcher, i.e., when repo is used by bitbake.

How can it work? The repo source, which is fetched by the repo wrapper, 
will not be in DL_DIR or handled by bitbake at all. This means the 
repo wrapper will try to contact googlesource.com directly and fetch it 
when it is run by bitbake, which cannot work since the host is 
disconnected from the network. How or from where would it be able to 
get the sources it needs?
