comments from #87: * cbed5408dddccae5589bcef73c5aeedeed06b8e5 For some reasons Nailgun thinks that it's server broke the connection and returns 227 instead of 0 We'll just handle this here instead of fixing the nailgun client itself. * 7810d4a44563f7a5dddff7fca2e11e7191979bbe It also sometimes breaks on 229 on the devbox. To complete this whole madness and made future 'fixes' easier I added this nice little array...
