false negatives on pypy
We are facing unexplainable behaviour over at urllib3.
After every run a subset of a certain number of lines is reported as uncovered.
I have added
print() statements before those lines. And indeed although my text is printed to the screen the the line is again reported as uncovered.
py26, py27, py32 and py33 work fine. Occurs with 3.6 and current default (c6743d8).
