[issue11089] ConfigParser 50x slower in 2.7

[Vasilis]

New submission from Vasilis <Vasilis.Vlachoudis at cern.ch>:

The ConfigParser class in 2.7 is almost >50 times slower than in the 2.6 which for large files it renders it almost unusable. Actually the speed decrease depends on the amount of the stored data
