Mastodon's tootctl utility provides a --background option for some tasks, which queues work into Sidekiq and allows the utility to exit quickly. This is primarily intended to allow a fire-and-forget use that doesn't require admins to keep an open terminal or screen/tmux for long periods of time. However, it has some downsides as it can overload Sidekiq and Sidekiq can overload other services.
