// The CJS_Global object is not the V8 global object (i.e. it is not |this|
// in JavaScript outside of a bound function call). It is a facility for
// sharing data amongst documents and persisting data within a document
// between sessions. It is only partially implemented due to security and
// privacy concerns. It provides access via properties in the usual manner,
// execpt that these are stored on the C++ side rather than in V8 itself.
// It is a static object that is available as "global" property of the V8
// global object and can be manipulated from JavaScript as |global['foo']|
// for example.
