Thanks for the suggestion, Allen. No, I had that set on all along.
The behavior was as described with that setting turned on.
I set this machine up only a few months ago, and rememeber looking for
a power-on-display-dimmed combination, and remember being disappointed
that it seemed to have disappeared between 10.6 and 10.11.
In writing the message to the list, I double-checked my settings, and
saw "Prevent computer from sleeping automatically when the display is
off" was unchecked. I have to believe that option only became
available consequent to an upgrade, because I surely would have turned
it on at the time.
Now that I have turned it on, the situation is much improved. It's now
5 days since posting my message, and I have not had to restart emacs
during that time. That returns me to status quo ante: remote
connections stay up as long as the machine stays up.
I don't know if "napping" while honoring TCP/IP is technically feasible
on the MacBook Pro hardware. That is, I'm not sure enough power, if
any, can be saved while remaining fully able e.g. to answer to ping and
accepting window updates from remote X clients. I would think it's a
desirable feature, quite apart from X per se. Has it been looked
into?
