-/** Shift arguments for new connections left by one.
+/** Set arguments for new connections.
  *
  * FIXME This is an ugly hack to work around the problem that parallel
  * exchanges are implemented using parallel connections. When we create
- * such a session via a naming server, the naming server shifts the
- * arguments for the initial connection, but not for the latter connections.
+ * a callback session, the framework does not know arguments for the new
+ * connections.
  *
  * The proper solution seems to be to implement parallel exchanges using
  * tagging.
