Investigate process.exit() and node.js termination

[justus-hildebrand]

When process.exit() is called, an exit event seems to be dispatched. To figure out how to properly handle this in our terminate method, we need to understand how this works. Is it added to the event queue? Is the event queue cleared before? Is the event dispatched outside of the event loop?

According to your findings, modify node::lib::Terminate().
