Re: display-time, mail-icon and POP3 mailboxes

      (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))

There may be a timing error here: each call to process-status allows
the value to change.

Perhaps the sentinel should be passed as an argument to
open-network-stream, so that there is no time at which the
connection is open and has no sentinel.
