	tagged types.
	(Expand_Cleanup_Actions): Rename the call to Has_Controlled_Objects to

	depending on whether they contain tagged types.

	* s-tasren.adb (Task_Do_Or_Queue): Previous code was reading
	Acceptor.Terminate_Alternative without locking Acceptor, which causes a

	can be off by 1 (either too high or too low). The solution is to lock
	Parent unconditionally, and then lock Acceptor, before reading
	Acceptor.Terminate_Alternative.
