Yes, thanks.  This has the advantage that we don't have to fix it, but
also the disadvantage that we can't fix it.

It's something of a relief that it's not Emacs's bug, so close to the
25.1 release.  I think I'm just going to learn to live with it - after
all, it only happens after many hours of Emacsing, and I have a
workaround in restarting Emacs.

Assuming the bug is in the Linux virtual terminal, the effort to get
useful debugging info to the maintainers would be excessive.

Alternatively, it's already been fixed, and I just need to upgrade my
kernel.
