I'm about too, There was a talk at Usenix about this reordering and the
stats given there it would appear to have a high impact to CPU time, after
some advice from cgd, I'm about to profile for a bit to find out if
the slowness really is in FFS, I'm almost fully convinced that it is...

I'd be real interested to hear from anyone else concerning this?

Neil.
