By the way, this is the wrong signature for an async callback.
It actually gets an IAsyncResult as an argument.  You'd have
to write something like

def callbackFunction(ar):
	ar.AsyncState.Close()

The immediate need could probably be fixed by adding the following
function to PythonEventHandler:

	public void Handle(IAsyncResult ar) {
		Ops.Call(func, ar);
	}

This wouldn't do much, though, for the next delegate that has a
different signature.  Ultimately, you probably have to reflect
the delegate's type and build a class to return to CreateDelegate.
