Hello Thomas,

I think you are overly pessimistic. Most of below issues are
non-blocking or at least we have work around, so we can hopefully
release in time.

Yes, this is non blocking.

Non blocking for me. Of course we should fix that but we should not
target a perfect release.

Yes, let's increase rendering time to 30 min or 40 min. If Paris does
not fit in that time, then yes we have an issue.

This one is a real issue I think.

I think this is non blocking. We can even deactivate this style sheet,
and reactivate it once it is fixed.

This is also a blocking issue. Hopefully the memory issue is related
to our rendering daemon. Let's try the ulimit approach.
