Subject: Refactor IScriptInstance / IScriptEngine to use a generic
 IScriptWorkItem, which is a thin wrapper around a IWorkItemResult from the
 SmartThreadPool. However, it is very easy to reimplement on top of basic
 threading and therefore makes the IScriptInstance class independent of the
 specific threading implementation.
