* Permission to modify threads or thread groups normally not accessible

* {@link SecureSM} enforces ThreadGroup security: threads with
* {@code RuntimePermission("modifyThread")} or {@code RuntimePermission("modifyThreadGroup")}
* are only allowed to modify their current thread group or an ancestor of that group.
*
* In some cases (e.g. test runners), code needs to manipulate arbitrary threads,
* so this Permission provides for that: the targets {@code modifyArbitraryThread} and
* {@code modifyArbitraryThreadGroup} allow a thread blanket access to any group.
