Why a timer is required ?, my expectation is that my function be called when the client socket is ready for write again. My function is encoding video packets so i expect this: 1. initial handler called, setup the write event callback 2. once the client socket is ready for write, invoke my write_event callback 3. write the packet 4. repeat #2 and #3 until the callback decide to finish the request is that possible ?
