btw, on my 6.2 it never changes 'Processes' count on 'S' press
and always shows all(+system ) procs (as if it in 'S' mode). Base top does it.

That is because 3.81 top has different semantics between active procs
and total ones.
'Processes' count displays active procs (+ threads in 'H' mode).

My small patch represents this. The first number displays actually
displayed procs(and threads)
and the second one displays all procs(and  threads) in system.
