Honestly I don't recall. The commit log tells you the problem I was trying

it was waaaay faster to copy the thread maps.
This could have been an oversight. I might have falsely assumed tgid ==
ppid?
Are you finding a problem with it?
rebasing my scheduling timehist command to 4.0 and this change breaks
one of the options. If there are no objections I'll send a patch along
with others to set ptid and ppid to -1 (that's what it is in 3.12).
Thanks,
David
