This was discussed today at length. The remaining issues are discussed in the bug[1] (comments 29 and 30). As it stands now, two items remain: 1. low memory killer and/or OOM is called more often with webbrowser-app and webapp-container using oxide than with qtwebkit 2. appmgr is not cleaning up all the stopped processes when a process in the process group is killed For '1', for compatibility with 13.10 webapps in the store, webapp-container and webbrowser-app load *both* qtwebkit and oxide and detects which to use at runtime. This is likely the cause for the OOM, though the webapps team will need to comment on if/when/how this will be fixed. Perhaps '1' it can be fixed with some dlopen magic? For '2', Unity's appmgr needs to be a little smarter and notice that if the leader is killed, the other processes in the process group need to also be killed. There are a couple of variations on a solution for this, the merits of which are being discussed. '2' should not affect webapp-container on the desktop since applications are not managed by appmgr at this time (ie, the timing of 14.04's release needn't play into its priority). Chris and the Phonedations team will work together on a patch for this starting tomorrow. This won't be available in the image until next week (at the earliest) though. Should this block image promotion? IMHO '2' should not block if '1' is fixed since we shouldn't hit '2' very often. I'm less sure if '1' is not fixed-- perhaps this is another case where we let it through this time but block for next promotion?
