Sure. It does mean that fixing deficiencies in the system is more
important than if it's just collecting patches and only needs to
be interacted with by a few people.

It's a feature I'd really like to see, and upstream sounded
receptive to it:
http://lists.ozlabs.org/pipermail/patchwork/2011-January/000348.html

so it would be great if we had the resources to do something here.

Basically, some qemu patches I send just get committed, which
is the straightforward case. Some patches don't get any review
comments of any form, so they "time out" and I eventually try
to batch them up and resubmit them via a pull request. I want
to be able to distinguish the 'timed out' patches from the others.

So "waiting for review" means "patch has gone on list and hasn't
had any comments"; "will put into next pull req" means "patch has
gone on list, had no comments but it's been a couple of weeks
so I consider it to have passed review by default"; "pull request
sent" means "I've sent upstream a pull request email but am waiting
for upstream to actually pull (or deny, as the case may be)".
"committed" means "actually got into upstream's git tree".

I'm not wedded to this particular set of states but it might
be nice for my purposes to have a little more flexibility.
I'll have a go with the existing set of states for a bit and
that ought to give me a better idea of whether I really need more.

Looks like you can, yes. So not being able to do that from the
project page is just a UI inconsistency.

You could mark the first patchset as 'superseded', I guess. With
the bulk-edit feature that's less effort than if it had to be done
one patch at a time.

This case is currently sufficiently uncommon that I can probably live
with out of band tracking via wiki page if necessary. It would be nice
to know whether it's a '2 hours of coding' or '2 weeks of coding' level
feature though :-)

It's a bit variable, since I only usually have to try the pull-request
approach if other people upstream have been too busy to review/apply
anyway. It doesn't kick in often.
