  abstract= "This paper suggests an additional semantics to XCHANs, where
     a sender to a synchronous channel that ends up as a
     component in a receiver's selective choice (like ALT) may
     (if wanted) become signaled whenever the ALT has been (or is
     being) set up with the actual channel not in the active
     channel set. Information about this is either received
     as the standard return on XCHAN's attempted sending or on
     the built-in feedback channel (called x-channel) if initial
     sending failed. This semantics may be used to avoid having
     to send (and receive) messages that have been seen as
     uninteresting. We call this scheme feathering, a kind of low
     level implicit subscriber mechanism. The mechanism may be
     useful for systems where channels that were not listened to
     while listening on some other set of channels, will not
     cause a later including of those channels to carry already
     declared uninteresting messages. It is like not having to
     treat earlier bus-stop arrival messages for the wrong
     direction after you sit on the first arrived bus for the
     correct direction. The paper discusses the idea as far
     as possible, since modeling or implementation has not been
     possible. This paper's main purpose is to present the idea."
