show thread as process

[Fabian Meier]

Yes, but I have the requirement to make the ps act like on a
linuxthreads system.
Well, the original procps has also an "H" option which will show the threads.

THREAD DISPLAY

H		Show threads as if they were processes


I don't know how it is implemented. But I guess it will also parse the
/proc/<process>/task directory?
Maybe I should add an "H" option to busybox ps.
