Abstraction can only be taken so far, Python strives to be a system/platform independent language and the sys module being what it is has to be platform specific and cannot be implemented in pure python.

The sys module is implemented in C: http://svn.python.org/view/python/trunk/Python/sysmodule.c?view=markup

There is no Python source for it, because it's entirely operating system interfaces that cannot be implemented in pure Python.
