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.
