Hmm. pwait can get the psinfo as of when the process exits,
by using poll(2) to wait for the process to exit; the way I read
proc(4) suggests that should work on /proc/*/usage (or /proc/*/lusage
if LWP-level detail is desired) as well.

Certainly I don't want to slow down one thing getting added by piling on
a bunch more; was just looking for a reaction.
If you want this on some other list, please CC whichever you think most
(discuss, rfc, code, whatever...). I have a few thoughts on how the things I
might look; if I find some time, I might just try my hand at some code along
In particular, I see the default format for additional usage info being
modelled on the
rusage(1b) output, since that's already familiar, and prusage contains
equivalents to all
but the last four fields reported by rusage, at least two of which are
apparently no longer
