executing a callback function in the second environment supporting the second computer language in response to the occurrence of the event associated with the object.
8. The method of claim 1 , wherein the reference count for the object comprises a number of at least one of references, pointers, or handles to the object from both the first environment supporting the first computer language and the second environment supporting the second computer language.
