Yes, clearly it's not a feature.  It's just the way it works and has
worked for the last many years.  The X11-vs-tty problem is new, but the
same issue was present long before if you have several X11
connections open.

Hmm... so you're suggesting that "-c" would means something like "open
a new frame just like starting a new Emacs would do"?  I guess that
would make sense.


PS: In any case, I think my "affinity" idea is needed/useful in the
non-"-c" case, so we should implement it anyway.
