Yes, my last message is a trimmed version of my next to last message (which itself is a trimmed version of all the verbose of the build, showing just after the PGO interpreter wakes up). Although, obviously they where run at different times (one run completed in 31 minutes while the other was in 35 minutes), because I no longer had the output of my next to last message available.

Other than that, the messages are 'identical'. The commands followed to get to this are:

git clone git@github.com:neyuru/cpython.git
git remote add upstream git@github.com:python/cpython.git
git remote -v
cd cpython
git checkout 3.6
