Domains are 0.10 specific I believe, and 0.10 is still bugged in few areas. I'd stay on 0.8.23 for quite some time since we are talking about stability.
Also domains are in 0.8
Regarding bugs, there are too many to list, just see the tracker and spend some time browsing through them https://github.com/joyent/node/issues?direction=desc&pag... I'm fairly sure you can find pretty much anything.
I'm considering removing all the npm modules from my project and go raw, since most of the obscure bugs are in the ecosystem anyway.
Somehow I missed domains are also in 0.8, thanks!
With the changes to streams in 0.10, I can understand it having some issues. That slipped my mind... but I don't do much streaming so I just assumed it worked.
