#ifndef HANDLE_WRAP_H_

namespace node {

// 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.
