Having the UI process die when a web process dies interferes with development. 1025296 1 235636 mrowe 2014-07-28 16:21:36 -0700 Created attachment 235636 Patch 1025351 2 235636 commit-queue 2014-07-28 17:56:37 -0700 Comment on attachment 235636 Patch Clearing flags on attachment: 235636 Committed r171715: <http://trac.webkit.org/changeset/171715> 1025352 3 commit-queue 2014-07-28 17:56:39 -0700 All reviewed patches have been landed.
