+# Echo back a unique integer value, and prepend to response a
+# leading sentinel byte (0xFF) the client can check scan for.
+#
+# 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. It must be issued upon initial
+# connection, and after any client-side timeouts (including
+# timeouts on receiving a response to this command).
+#
+# After issuing this request, all guest agent responses should be
+# ignored until the response containing the unique integer value
+# the client passed in is returned. Receival of the 0xFF sentinel
+# byte must be handled as an indication that the client's
+# lexer/tokenizer/parser state should be flushed/reset in
+# preparation for reliably receiving the subsequent response. As
+# an optimization, clients may opt to ignore all data until a
+# sentinel value is receiving to avoid unecessary processing of
+# stale data.
+#
+# Similarly, clients should also precede this *request*
+# with a 0xFF byte to make sure the guest agent flushes any
+# partially read JSON data from a previous client connection.
