Nice summary, thanks! In any case, I think it would make sense for open-network-stream to have an optional 5th argument which serves two purposes: If it is omitted or nil, the current blocking connect is used. If it is non-nil, a non-blocking connect is attempted - if supported by the o/s (and the emacs code) - and when the connection is established, the argument (which must be a function) is called to initiate using the connection. The arguments to that function will probably be the process and buffer (this is still TBD). If the o/s (or emacs) does not support non-blocking connect, a blocking connect will be performed - and the supplied function will simply be called before open-network-stream returns (it may need an arg indicating whether a blocking or non-blocking connect was made to arrange for different things to happen when open-network-stream returns). -- Kim F.
