2.9 must-fix bugs.

I have been working through the 2.9 must-fix tagged issues on the Github.
github.com/LinuxCNC/linuxcnc/labels/2.9-must-fix

But that list was created during the Madison meetup, several months ago, and it is
possible that there have been other issues raised since that should be
tagged as such.

Does anyone want to suggest any?

I am vaguely hopeful of releasing 2.9 in the next couple of days. Not
that anything internally has really changed to prompt this, it's more
about the upcoming debian point release focussing my mind.
