I don't think it's right to change /proc/pid/task/tid/status this way.
The real status is true and correct for the individual task, no matter what.
If you want to change /proc/pid/status, then you ought to split it into
proc_tgid_status and proc_tid_status variants to differ this way.

I don't really have an opinion either way about this for /proc/pid/status.
We've known it behaved this way for a very long time, and I've always
considered it procps's problem to display such situations in ways that
users find most useful.  It can already quickly tell that situation by a
"Threads:" line with >1 when "State:" says "Z".  If you do change it, it
might be nicer to display it as a (compatible) special case:

State:	S (delayed-leader)


Thanks,
Roland
