mentoring the previous procfs implementation

+ <pinotree> hm, why /proc/$pid/stat is 600 instead of 644 of linux?
+ <jkoenig> pinotree, it reveals information which, while not that sensitive,
+ would not be available to users through the normal proc interface.
+ <jkoenig> (it's available through the ps command which is setuid root)
+ <jkoenig> we discussed at some point making it 644, IIRC.
+ <pinotree> hm, then why is it not a problem on eg linux?
+ <jkoenig> (btw you can change it with the -s option.)
+ <jkoenig> pinotree, it's not a problem because the information is not that
+ sensitive, but when rewriting procfs I preferred to play it self and
+ consider it's not procfs' job to decide what is sensitive or not.
+ <jkoenig> IIRC it's not sensitive but you need the task port to query it.
+ <jkoenig> like, thread times or something.
+ <pinotree> status is 644 though
+ <jkoenig> but status contains information which anyone can ask to the proc
+ server anyway, I think.
