export asyncdispatch handles

[ringabout]

I need handles attributes to make httpbeast work in windows. Now It seems to be fine to use select(windows) with httpbeast.

  let disp = getGlobalDispatcher()

  for h in disp.handles.items:
    selector.registerHandle(nativesockets.SocketHandle(h), {Event.Read},
                            initData(Dispatcher))

Document it please as an internal detail of the current implementation that might be changed.

I'm not sure which way is better? Export it or add a getIoHandles (which is specific to windows)?

I would export it. A getter doesn't help much.
