Right, sorry to have mixed those.

I dont think a separate list would work. Some patches would still be
posted to the ML, some not, it would end up as a mess. Something
picking up patches and putting them on bugzie or gerrit could work
though (with the option for people to publish patches there personally).

This should be an nonissue for most things with gbuild and tail_build.
Unfortunately binfilter currently messes that up quite often.

Sounds good. Norberts proposal is also good, even if a little bit more
Also, as of now, I might get a nagmail from the tinderbox simply
because I commited to a known broken build, making me feel less
responsible. I still want that mail to go to all commiters since the
last good build. But it would be great to explicitly point out the
commiters and commits to the _first_ build that broke, because they are
most likely guilty.

True. I was thinking more along the line of having the "unreviewed"
branch serving primarily as a review queue. Doing a tinderbox builds
over them is just a bonus. Anyway: Having an opportunity to have any
bigger set of patches tinderboxed before they hit master would be a big
An alternative is to do it the other way around: Create a branch
"tinderboxed" that regularly pulls from master up to the state that:
- windows has build and smoke/subsequenttested
- any one unix platform has build and smoke/subsequenttested
- is not known to be broken on any platform
It would provide a good point for rebases and starting branches.

I dont think we should schedule a you-have-to-be-there-date. Maybe we
will just try to have a look around on Monday 15:00 UTC on IRC and
harvest for patches with whoever is there? No oligations etc. Just a
nice informal half an hour of hug-a-patch.
