In between I can confirm that we get the slowpath problem back with my
patch, so we still have a bug somewhere. Reverting your commit would
be just a band aid. I think it is better to find the bug and do a real
fix instead. Unfortunatly I fear I'm not able to track it down before
my vacation that starts tomorrow. I'll continue to work at it once I'm
back...
