Just wondering, how much demand is there for continued 1.x maintenance? I think 1.x (and 3.x) are both fairly bug-free by now and unlikely to need much, but I''m willing to commit to long term maintenance if people want it. Maybe we can drop it when the Ruby core team stops supporting Ruby 1.8?[1] AFAIK, Unicorn 3.x with its kgio dependency currently works on all *nix-like platforms with fork() support, even ugly non-Free OSes that aren''t _officially_ supported. Unicorn 4.x adds the dependency on raindrops, but I think that would cause fewer portability problems than kgio introduced with Unicorn 3.x. Time will tell... [1] For the record Unicorn 3.x/4.x works great with Ruby 1.8 and Unicorn 1.x works well with Ruby 1.9, too. However, Ruby 1.9.2 introduced a performance bug[2] that got me experimenting with kgio. While this bug is fixed Ruby 1.9.3, but kgio is still faster. [2] http://redmine.ruby-lang.org/issues/3905 Thanks for reading! -- Eric Wong
