What is rare about my case? Assuming the (message "") gets removed from
info.el, there are just 3 things needed for the long delay to happen:
(i) Having a large .emacs.desktop;
(ii) Not encountering any error message during its loading.
(iii) Not getting any messages from flyspell and friends or the OS
during loading.
This will be a common case amongst users.
In particular, the problem is NOT confined to the tty. It will occur on
GUI sessions, too. When I tried it out this morning under X, the only
thing which triggered a redisplay was a version conflict error between
CC Mode and js-mode (and some status messages from shell-script-mode
very late in the loading).
My current idea is to count the buffers in desktop-save, and to output a
message:
Restoring buffers: 127/166
as we restore the buffers. We already count the buffers as we load
them.
This is NOT complicated.

I think this is the case, yes. There's not a lot of information about
it in the git log.
