+* This interface provides access to the execution stack of a thread.
+* It has several subclasses to distinguish between different kinds of
+* stack frames: these currently include activations of Java methods
+* or JavaScript functions.
+* It is possible that synchronize blocks and try blocks deserve their own
+* stack frames - to allow for later extensions a debugger should skip over
+* stack frames it doesn't understand.
+* Note that this appears very Java-specific.  However, multiple threads and
+* exceptions are relevant to JavaScript as well because of its
+* interoperation with Java.
