  What you describe is implemented in both of the irc clients I
mentioned.  They update the mode-line tracking indicator when new data
arrives from the process, but this is not often enough, and it is the
situation I would like to improve upon.  A typical case for the new
feature would be as follows:

  I have an emacs frame open on workspace 1, and my mode-line indicates
that there is activity in an irc channel.  I switch to workspace 2,
where I have a frame showing the active irc channel.  Without the
ability to use the make-frame-visible event, the mode-line tracking
indicator will continue to show that buffer, possibly for minutes until
more data comes from the process.  If I switch back to workspace 1, and
the tracking indicator still has not been updated, I cannot then know
when the next new data arrives from the process, because the indicator
is now falsely on, though I have already read the buffer.

  I guess I am not sure what the point of having a make-frame-visible
event is, if there can only be one handler on it.

  Thank you for your time.  I hope you will reconsider.
