Thanks for that.  Thanks too to Simon and you for your feedback regarding my
initial patch.

There is a minor annoyance when ps displays a multi-lwp process and
-H is not used: only the most recently created lwp is displayed because
proc.p_lwps is a LIST and so lwp_fork() adds new lwps in front.  IMO
it would be less consuming if ps displayed the initial lwp.

Doing so could be done if p_lwps were turned into a TAILQ.  This seems
feasible as there are less than 10 occurrences of p_lwps and the added
RAM footprint to struct proc is small.

What do you think of this? Is it sensible?

Thanks,
Nicolas
