RFC: lei-daemon and auto-up

[Konstantin Ryabitsev]

Hello:

Since lei-daemon is already up and running, would it be possible to tell it to
automatically "lei up" things at certain intervals?

Maybe something like:

    [lei]
      q = [...]
    [lei "q"]
      output = [...]
      include = https://lore.kernel.org/all/
      external = 1
      local = 1
      remote = 1
      refresh = 300

That would allow folks to automatically get updated info without needing to
set up cronjobs or systemd timers.

Yes, something along those lines...  It should at least fall
back to refresh intervals if network connectivity is lost or
HTTP servers w/o support for long-polling.

The ideal thing would be to POST HTTP requests that do
long-polling against -httpd and let curl wait on the response;
similar to IMAP IDLE.

-httpd will probably trickle zero-byte gzipped responses at a
regular intervals to keep connections alive if there is no data,
yet.

There's still a lot of things I want to do w/ inotify and
IDLE(-like) real-time notifications (including the new
public-inbox-fetch command).  I don't like polling as a first
choice.

Also.  I'm not sure what ways exist to be notified on network
up/down events on Linux or *BSDs w/o polling.
