[pypy-issue] [issue926] pyparsing: PyPy takes much more time than CPython

[hruske]

New submission from hruske <zejn at kiberpipa.org>:

I implemented a parser in pyparsing, which has absymal performance in PyPy.
Using the parser on smaller dataset results in PyPy being ~10x slower (14.9s)
than CPython (1.5s) and failing to complete on a large dataset, where CPython
takes 17s.

Script and dataset can be found at http://www.kiberpipa.org/~hruske/stuff/pypy/
