[pypy-svn] r45033 - pypy/dist/pypy/lib/test2

New Revision: 45033

Added:
   pypy/dist/pypy/lib/test2/test_stackless.py
Log:
stackless pickling is broken. This test breaks because we are pickling main via the parent. lib/stackless does not yet use usercostate. Also, pickling parent is generally a bad idea. I guess the parent must go away
