I'm not entirely sure about the name, but it's probably fine. There should
be some comments somewhere making clear what "nr" or kind of threads this
refers to. This is threads created and not yet reaped. It differs from
the "threads not yet exited" (signal->live) count only during some races
around exit time, and when ptrace is preventing self-reaping.
