Not at this time. I can imagine that there is proc manpage that might
need a line or two of Documentation.
I am not familiar with anything in Documentation that descripes any of
this and would benefit from an update. From an overview perspective I
can see documenting this so people know thread-self exists. From an
actual usage perspective:
$ ls -l /proc/thread-self
lrwxrwxrwx 1 root root 0 Aug 1 00:00 /proc/thread-self -> 484/task/484
seems like pretty comprehensive documentation to me.
