Working with a customer this week with this issue. They create mulitple subprocesses from an actionHandler, each of which can execute several nodes, which possibly started other subprocesses, etc, and then signalling the parent token whne complete. They were having issues with the call stack. Their solution was to create additional threads on their own. How does delayed execution differ from asynchronous continuations?
