Use GitLab with only 1 Unicorn worker?
Following previous discussion in omnibus-gitlab!822 (comment 12455439)
Currently we need at least 2 Unicorn workers for GitLab to function correctly: any functionality in the web UI that creates a commit and it supposed to fire Git hooks will cause internal API calls. (Example: web editor) If a GitLab installation has only one Unicorn worker it will become tied up handling the user's request (e.g. update a file in a repo) and will be unable to service internal API requests needed by the Git hooks.
Can we do something about this? Do we want to?
