If I am reading that correctly, it is fixed in 18.04. May have to upgrade before the official release data if I want to get any work done.
In the comments in the above link, a solution was provided. I've been running this and have had no issues with the gnome-software process.
sudo apt-add-repository ppa:ubuntu-desktop/gnome-software
sudo apt update
sudo apt upgrade
Then reboot.
I am marking this answered.
