#9 echo sample is not working

[Noam Hoffer]

Using mod_snake 0.5.2 and apache 2.0.28
the 03_mod_echo.py in the tutorial is not working.
It uses conn.write and conn.read which are not
supported for apache2.
Instead it should use something like
conn.input_filters.get_brigade for reading input from
the client. But there is no such function.
Furthermore it generates a segmentation fault
(something to do with the python error message)
