Rik,
Don't you think that it would be much easier if we just implement "kill priorities" which applications will set themselves? Certainly, only a limited range of the priorities will be available for non privileged applications. If people think that this application is something special (like X or long standing computation programs or anything else) they set a non default killing priority for the process. Among other applications it isn't matter which one will be killed first.
Best wishes Andrey V. Savochkin
