group Children started in parallel if startStopThreads > 1 (Engines and Hosts only)
Container -> Child ++: start()
note right of Child
Engines have Hosts as children.
Hosts have Contexts as children.
Contexts have Wrappers as children.
Children are containers so the
process on this diagram is
repeated for each child.
Contexts do a lot more in start()
as shown in diagram 5.
