The own-thread code which preceded the current poll implementation did something similar, using a pipe fd to be woken up for new *outgoing* messages. That code still exists, and might provide some insight into how to do this for the current poll code. _______________________________________________ Gluster-devel mailing list Gluster-devel@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-devel
