[pypy-dev] [pypy-commit] pypy default: hidden frames are fairly rare, it's ok to unroll this

[Alex Gaynor]

Hi Carl,

At the moment this shouldn't affect anything, this function is only called
in other places with loops. However, this is based on the same logic we
used in getnextframe_nohidden, and I believe is a first step in making
sys.exc_info() not explode stuff :)
