api.drupal.org is a good test case for single sign on, it is a separate site and is getting a new feature that needs user logins, commenting.
chx made commenting work, http://drupal.org/node/101308, but I want to deploy this right. Comments about improving the documentation itself really should be improved documentation, it should be easy to file an issue to get the process started; http://drupal.org/node/500536 and http://drupal.org/node/512824 currently need work.
We need to get the docs team involved in managing this new community feature, to moderate comments. Tools like http://drupal.org/handbook/comments and http://drupal.org/tracker make this job easier.
David Strauss made a single sign on system, bakery (for browser cookies), http://drupal.org/project/bakery. Any issues there should be looked at.
Another big change is new file URLs. Variable-length URLs do not mix with MENU_MAX_PARTS. This puts in place the new URL scheme to start on http://drupal.org/node/218306 and http://drupal.org/node/179062, but those can wait for the next release.
Once development is finished up, everything will be deployed on staging sites for testing, which we need help on.

Comments
*_*
I could imagine how would the documentation look like, with more than 50 comments, making extra load.
Rather, we can offer a link to print the current page in .pdf format. This way user can store the pages and can access off line.
Also, I think its not making any sense to loging in to api.drupal.org just to post comments on a page.
We used to do this on d.o.
