This e-mail is to let you know that the commit spree is over for the day, with no remaining changes in the rwatson_sockref branch. There are likely bugs. You may find them. If you do, please e-mail bug reports, ideally including any panic messages, stack traces, reproduction cases, etc, to current_at_, and I will try to get to them as quickly as possible.
