From efdd06ed181a88a11e612238c1ac04668e665395 Mon Sep 17 00:00:00 2001 From: Robin Holt Date: Mon, 13 Apr 2009 14:40:19 -0700 Subject: sgi-xpc: implement opencomplete messaging sgi-xpc has a window of failure where an open message can be sent and a subsequent data message can get lost. We have added a new message (opencomplete) which closes that window.
