We actually continued to work on the fork until it was clear Bram wouldn't be responsive to any more changes. Once it became clear he wouldn't accept the patch we stopped wasting more time as we are trying to create a viable business. We weren't going to sink our startup for the sake of vim, as much as I love the editor. We spent a long time, it was a frustrating experience, so yes we tell the internet when it comes up. Any of the freezes we found we would have loved to patch back into vim had this gone differently, and it would have been a lot of work.
