I started looking into this - the likely culprit is this commit
https://github.com/python/cpython/commit/1a2dd82f56bd813aacc570e172cefe55a8a41504
which introduces parallel .pyc compilation. Previously (in 3.7) the
bootlocale.py file was compiled only once, and now I am seeing this in
log.do_install:

/home/alexander/development/poky/build-x86-64/tmp/hosttools/install -c -m
644 ../Python-3.8.1/Lib/_bootlocale.py /usr/lib/python3.8
Compiling
'/home/alexander/development/poky/build-x86-64/tmp/work/core2-64-poky-linux/python3/3.8.1-r0/image/usr/lib/python3.8/_bootlocale.py'...
Compiling
'/home/alexander/development/poky/build-x86-64/tmp/work/core2-64-poky-linux/python3/3.8.1-r0/image/usr/lib/python3.8/_bootlocale.py'...
Compiling
'/home/alexander/development/poky/build-x86-64/tmp/work/core2-64-poky-linux/python3/3.8.1-r0/image/usr/lib/python3.8/_bootlocale.py'...

I don't yet know how this file ends up being compiled several times, or
whether they indeed race.

Also I am still unsure how it ends up with the wrong ownership. Hints?
