This particular progressive slowdown of built-in AA is not due to the bug 
introduced with 2-040.  It was present in 2-039, and is also observable 
in the dmd, druntime (rev 265 for lifetime.d), phobos, built from latest 
SVN for the fixed 2-041

The pydict performance still 25% worse than fastest builtin AA, but does 
not slow anything down.  Once the builtin AA tests have been run, 
everything slows down, including the pydict.
