Whenever you fork a repository at GitHub, we give you a leaf repository
that points its info/alternates to a master "network.git" repository for
the fork network.  The network.git repo contains all of the objects, and
has a remote configured for each of the child repositories. You would
never want to gc in that repository without doing a "fetch --all" first.

Most networks have only a few dozen forks, but a few have a large number
(torvalds/linux has ~5K, and homebrew is close to 10K).  And then
sometimes a MOOC instructor tells an entire 50K-person class to fork a
hello-world project all at once. :)
