* This is a basic extension of ThreadContextPolicy that

+ * <p>Some more things to think about.</p>
+ *
+ * <ul>
+ * <li>Register a DemuxSecurityManager that redirects as
+ * appropriate to thread specific SecurityManager.</p>
+ * <li>Register a SecurityManager that noticies permission
+ * checks for top level windows and records all the
+ * windows in a WeakHashMap. Then when context is
+ * deactivated will dispose any still visible/non-disposed
+ * windows.</p>
+ * <li>When a System.exit() call is made throw a ThreadDeath
+ * exception rather than exiting.</p>
+ * <li>Force all threads to be created in a specific
+ * ThreadGroup.</p>
