I've never been quite sure what the complete todo list is. I got patches
for ls, mkfifo, mknod, mkdir, id, and cp, but I don't think that's a
complete list? (Ah, and here's one for stat...)

Dig dig dig... Ok I found chsmack, doesn't look too hard to implement?
(First I've heard of it, though...)

I have a pending patch for that, I just need to grind far enough down in
my todo list.

I thought I'd applied that one already?

(Rummage, rummage... yeah the plumbing's there. Did it not work when you
tried it? I don't have a smack build/test environment. I got a tizen
emulator working once but didn't have a compiler targeting it...)

I'm about 2/3 of the way through implementing ps, it's fairly high
priority to get back to but I'm traveling this week. (I want to include
it in the next release though.)

However, I don't think I ever got a -Z patch for ps? (First I've heard
of it having -Z, actually...)
