All of these are actually serious and we need to find a way to fix them. It seems bad to just say "they fail sometimes so lets expected fail them".
I agree. The intention is not to ignore them but to get the build server green so we can see if any new issues pop up. If we submit this patch, I recommend you open a ticket or find some way of tracking these urgent issues on your side.
The lldb build servers were recently demoted to "experimental" so llvm developers don't even get emails when they go red. I'm trying to get them stable so we can get out of experimental and they get notified when they break the build.
What do you think?
