Serhiy, I don't think it's fixed in 3.3, or perhaps I'm misunderstanding what you mean by "fixed". If you create readline.cpython-33m.so in your cwd and then run python, the fake readline will still be loaded instead of the real one.

For example (here with 3.4):

$ touch readline.cpython-34dm.so
$ ./python
Python 3.4.0a0 (default:2a0c9472c89c, Oct 21 2012, 23:24:06) 
[GCC 4.5.2] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import readline
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: ./readline.cpython-34dm.so: file too short
