# This class is instantiated by the `Puma::Launcher` and used
# to boot and serve a Ruby application when no puma "workers" are needed
# i.e. only using "threaded" mode. For example `$ puma -t 1:5`
#
# At the core of this class is running an instance of `Puma::Server` which
# gets created via the `start_server` method from the `Puma::Runner` class
# that this inherits from.
