I've just uploaded a new dev version of Geo::ShapeFile to CPAN which allows users to turn caching off.

https://metacpan.org/release/SLAFFAN/Geo-ShapeFile-2.63_001

Once that's installed, change the object creation line to be:

$shapefile = Geo::ShapeFile->new ("tabblock2010_42_pophu", {no_cache => 1});

It's an all-or-nothing approach, but should be sufficient for this use case. I might in future try to add a maximum cache size option.

Other ideas and pull requests welcome.
