For one benchmark we have, between 3.1 and 3.3, there were two patches 
that caused compile time speed regressions, the second was small and 
was eventually fixed or worked around with the physmem patch.  The 
first, was a ~30% speed regression in one tiny little patch.  This bug 
remains unfixed on the 3.3 branch.
