Fixed high CPU usage of XREQ channel....

Fixed high CPU usage of XREQ channel. Previously, the XReqSocketChannel was consuming nearly 100% CPU. This was caused by the ioloop polling for POLLIN|POLLOUT|POLLERR always. Now we are only polling for POLLOUT when there is a message waiting to be sent. This seems to have fixed the problem.
