The progress code in the frame threading also has data races as
defined by the C standard, so ThreadSanitizer also warns about it. I
submitted patches for that code to use atomic operations before.

Yes, I will create a patch to just merge the variables. My goal is to
fix the data races, so I still need to create another patch on top to
use atomic operations.
