* This interface provides access to the execution stack of a thread.

* 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.
