+A <code>thread</code> object uniquely represents
+a particular thread of execution
+and the right to join with it.
+That right may be transfered to other thread objects.
+A thread of execution is <dfn>detached</dfn>
+when no <code>thread</code> object represents that thread.
+Objects of class <code>thread</code>
+may also represent <dfn>not a thread</dfn> (referred to as NAT).
