Sorry, I didn't check all affects except performance regression,
and there was already related discussion and decided not to do:
https://bugs.python.org/issue24915#msg251128
'I think the --pgo flag needs only work in single process mode, since
multi-process would probably not write out the profiling data properly.'

I close the issue as won't do.
