Exactly.

You completely lost me there. A push (update) is done as a specific user, 
who should not be able to write to a _global_ file!

Nevertheless, "24175 calls to git" is sure as hell more expensive than 
"reading 24175 files".

Plus, if we integrate the functionality to write .git/info/refs-details 
into update-server-info, you can reduce that further: it is no longer 
per-branch, but per-repo.

Ciao,
