[pypy-dev] Open extremely slow when using "rU" flags

[Eleytherios Stamatogiannakis]

Hello to all, and thanks for the great work on PyPy.

There remains a very problematic case in PyPy, where PyPy (tested with 
nightly) is around 193 times slower than CPython.

This happens when reading a file using the universal newline flag ("rU").

Are there any plans to fix this problematic case, or should we just 
avoid using it when running under PyPy?

Kind regards,

lefteris.
