/**

* The Ruby object represents the top-level of a JRuby "instance" in a given VM.

* JRuby supports spawning multiple instances in the same JVM. Generally, objects

* created under these instances are tied to a given runtime, for such details

* as identity and type, because multiple Ruby instances means there are

* multiple instances of each class. This means that in multi-runtime mode

* (or really, multi-VM mode, where each JRuby instance is a ruby "VM"), objects

* generally can't be transported across runtimes without marshaling.

* This class roots everything that makes the JRuby runtime function, and

* provides a number of utility methods for constructing global types and

* accessing global runtime structures.
