This issue tracks the current limitations of builder as a clustered system
It uses a filesystem based lockfile to prevent 2 or more git pushes at the same time
In a multi-builder setup, this means that multiple git pushes can in fact happen at the same time
To solve, the lock will need to be distributed
It keeps git repositories on disk and runs pre-receive hooks on them to deploy
In a multi-builder setup, this means that one git push may only have to push a few refs, while another identical git push may have to push all refs. Not the end of the world
To solve, the refs list will need to be moved off of local disk to a shared location (object storage?)
