class Async::Node

def terminate

Immediately terminate all children tasks, including transient tasks. Internally invokes `stop(false)` on all children. This should be considered a last ditch effort and is used when closing the scheduler. 
def terminate
	# Attempt to stop the current task immediately, and all children:
	stop(false)
	
	# If that doesn't work, take more serious action:
	@children&.each do |child|
		child.terminate
	end
	
	return @children.nil?
