[pypy-svn] r52978 - in pypy/dist/pypy/lib: _ctypes app_test/ctypes

[fijal at codespeak.net]

Author: fijal
Date: Thu Mar 27 03:54:49 2008
New Revision: 52978

Modified:
   pypy/dist/pypy/lib/_ctypes/function.py
   pypy/dist/pypy/lib/app_test/ctypes/test_callbacks.py
Log:
fix callback issues. IMO something is wrong with leak checks (or these
tests are leaking). Leave skipped test not to forget.
