Thanks for the review and testing!
I'll push a V2 with the indentation fixes soon.
this deletes the global vars before it deletes the references to them. That's gonna be a real pain for bisections, please can you restructure the series to prevent intervening build failures? (i.e. if I apply just 1/4, the selftests don't compile).
Could you help me understand this better? The selftests don't compile either way if both 1 and 2/3/4 aren't applied at the same time.
