Looks like we need swap after all. Swap on flash sounds crazy, but this would be a place where non live pages can be dumped. I assume the majority of the memory that causes problems like this is leaked memory or regular bloat.
There seem to be some proposals how to make oom-kill behave more cooperative. But when oom-kill comes, every thing is too late in my eyes.
