#docker_build_lock_path ⇒ Object

Lock serializing access to the shared repo dir at docker_build_base_path across concurrent deploys on the same build host (see README for the race).

Keyed by basename, not a fixed name, so unrelated consumers sharing a parent directory don't serialize against each other.
