With inliner performance fix I am going to push out today, the situation looks

So memory use is somewhat up (4GB compared to 3.2GB) but Mozilla grew a bit,
too, so I think there are no important changes since my last report.
Performance wise we are in better shape than 4.7 release (I will backport the
fix, 4.7 needs over 10 minutes in the inliner) but we still are way too slow,
with over 3 minutes needed for streaming in..
