Actually, let's back-track..
Did you try the other approach? Make /proc/self point to the thread
instead of the task?
The thread-group leader seems to have these extra files:
- autogroup, coredump_filter, mountstats, net, task
but quite frankly, at least "net" and "task" look like they should
exist there - with "task" pointing back to the actual task (it would
make more sense for "/proc/<pid>/task" itself to be named "threads",
but whatever).
Yes, it would be semantically different, but it would mean that
"/proc/self/fd/" would actually make sense in a way that it currently
does *not* - which would seem fairly important, since the primary use
for it tends to be /dev/stdin.
And the other semantic differences might be much harder to notice.
Worth testing?
