+
+If we can't send all of the data, move the remaining data to the
+start of the buffer so that we can send it again later.
+
+See #111

+Subject: [PATCH] protocol: improve flushing
+
+Use the IO_OUT flag to schedule flushing instead of a flush_event.
+
+Handle EGAIN and wait for IO_OUT to try again.
+
+Fixes #111
