Comment(by SimonKing):
Aha! That's how an influence of the operating system is possible:

In other words, lazy class attribute does not work on OS X!
Jeroen, you said that sage works on OS X with #9138. Do you mean that all
tests pass? Including tests for lazy_class_attribute (I hope there are
some tests)?
