+# @guest-sync:
+#
+# Echo back a unique integer value
+#
+# This is used by clients talking to the guest agent over the
+# wire to ensure the stream is in sync and doesn't contain stale
+# data from previous client. All guest agent responses should be
+# ignored until the provided unique integer value is returned,
+# and it is up to the client to handle stale whole or
+# partially-delivered JSON text in such a way that this response
+# can be obtained.
+#
+# Such clients should also preceed this command
+# with a 0xFF byte to make such the guest agent flushes any
+# partially read JSON data from a previous session.
