Yes, that sounds like a good idea.
The steps for making a non-blocking open-network-stream could be:
(defun my-stream-connected (p)
...)
(defun my-sentinel (p s)
(cond
((equal s "connected\n") ...)
;; connection established
(my-stream-connected p))
((equal s "failed\n") ...)
;; connect failed
)
(t ...)))
(defun ...
(setq p (open-network-stream .... t))
(when p
(cond
((eq (process-status p) 'connecting) ;; New return value
;; connecting, so set sentinel
(set-process-sentinel p 'my-sentinel))
((eq (process-status p) 'open)
;; non-blocking connect not supported, connected
(my-stream-connected p))
((eq (process-status p) 'closed)
;; failure...
;; will this happen? -- open-network-stream should return nil instead
(delete-process p) ;; necessary?
(setq p nil)))))
Doesn't seem to be too complicated to use...
