[pypy-issue] [issue1206] Extreme slowdown of code part (array.array) operations

[Pigmej]

New submission from Pigmej <jedrzej.nowak at codernity.com>:

See Attached code.

Script outputs:

- pypy 1.9:
root at ci:/tmp# pypy builder.py 
time 1715.36743188
process size 168648 kb

- cpython 2.7.3:
root at ci:/tmp# python builder.py 
time 0.507338047028
process size 31668 kb

Also pypy used 100% cpu during whole process.


As I can understand slow pypy with strings, following behaviour is really weird for me.

That part of code is from bigger context, so it might look a bit weird.
