Version 1.3.6
Add support for forceful termination of JavaScript execution.
Add low memory notification to the API. The embedding host can signal a low memory situation to V8.
Changed the handling of global handles (persistent handles in the API sense) to avoid issues regarding allocation of new global handles during weak handle callbacks.
Changed the growth policy of the young space.
Fixed a GC issue introduced in version 1.3.5.
