Moreover it takes more than 50% of the time when doing

              make TEST=T1535

which I do a lot

An error occured while writing the performance metrics to git notes.

            This is usually due to a lock-file existing somewhere in the git repo.

../../mk/test.mk:344: recipe for target 'test' failed

make: *** [test] Error 1

Should I worry?  it looks bad.

I definitely don’t want to monkey with git notes when I’m just developing/testing/validating, which I do endlessly
