OK, I won't object to closing this bug report, since the bug doesn't
seem to be happening (on Emacs 26.1 and master) at the moment.  I would
object to labelling the closure "not a bug" or "won't fix".

I do, however, raise an eyebrow at the "doesn't seem to be leading
anywhere" justification.  Bugs, particularly difficult bugs (as this one
is) tend "not to be leading anywhere" for a lot of their life times.  It
would be bad just to close such bugs for such reasons, rather than deal
with them.

On a Linux tty, this problem of C-g being non-functional happens to me
relatively often (several times a year), resulting in me having to kill
Emacs and start it again.  Unfortunately I haven't logged these
occurrences at all.  I strongly believe there is a problem in the
keyboard handling area of Emacs, though pinning it down is difficult.
