 /** Mark orconn for close and transition the associated channel, if any, to

+ * It's safe to call this and connection_or_close_for_error() any time, and
+ * channel layer will treat it as a connection closing for reasons outside
+ * its control, like the remote end closing it.  It can also be a local
+ * reason that's specific to connection_t/or_connection_t rather than

+ * rather than connections, use channel_mark_for_close(); see also
+ * the comment on that function in channel.c.
