Summary:
This sets
PYTHONUNBUFFERED
to improve local scheduler logging latency. With this set each python log line gets immediately written out so you avoid large blocks of logs from the buffering. It also preserves groups unlikereadline()
since a stack trace will be written out as a single writeThere's can still be some small amount of ordering mismatches but it's better than it was before
