New issue 2323: SCons slower on pypy

Daniel Holth:

SCons does a lot of `__class__` assignment with classes using `__slots__` and interestingly this didn't work on pypy even though the slots matched, so https://bitbucket.org/dholth/scons takes `__slots__` out with a metaclass.

Disregarding the issue that prevents it from running at all it is perhaps 20% slower, for example building the `local-zip` target. Perhaps that is interesting to you. Thanks.
