@short implement XEnumerationAccess interface as helper to create many oneway enumeration of tasks
@descr We share mutex and framecontainer with ouer owner and have full access to his child tasks.
(Ouer owner can be the Desktop only!) We create oneway enumerations on demand. These "lists"
can be used for one time only. Step during the list from first to last element.
(The type of created enumerations is OTasksEnumeration.)
