// Rules:
//
// - Do not throw from handle methods. Set errno.
//
// - MakeCallback may only be made directly off the event loop.
// That is there can be no JavaScript stack frames underneith it.
// (Is there anyway to assert that?)
//
// - No use of v8::WeakReferenceCallback. The close callback signifies that
// we're done with a handle - external resources can be freed.
//
// - Reusable?
//
// - The uv_close_cb is used to free the c++ object. The close callback
// is not made into javascript land.
//
// - uv_ref, uv_unref counts are managed at this layer to avoid needless
// js/c++ boundary crossing. At the javascript layer that should all be
// taken care of.
