Maybe 'latest-repository-commit' and 'update-cached-checkout' commit
can be modified to not use 'switch-to-ref', and instead directly ask
libgit ‘what's the tree structure of commit cabba9e’ and call a
procedure like 'add-file-tree-to-store'.  That would avoid lock files,
creating separate directories for concurrent checkouts, ...

Greetings,
Maxime.
