What steps will reproduce the problem?
1. Download a shapefile of 100+ mb
2. Run the .shapes() method

What version of the product are you using? On what operating system?
Mac OSX Lion, pyshp 1.1.6-beta

Created an iterator class within the reader class, to allow for large file

This is a great patch, and allows for instant processing of features. It would 
be great to have an iterator for the associated records too, available via the 
records and shapeRecords functions.

Fixed in version 1.1.7.  Added shapefile.Reader.iterShapes() and 
shapefile.Reader.iterRecords() methods which iterate instead of reading the 
entire data set into memory. The individual Reader.shape() and Reader.record() 
methods also use these iterators to find records.  The Reader.shape() method 
will try to use the shx index file first if available.
