Anuj Kumar had tried using our python with the latest requests package, rather than the rev we required. That highlighted that it was time to fix our incompatibility with the latest requests package.

I have updated to match the latest python requests package version 1.1.0. We are no longer compatible with 0.14.2 now. YOU MUST UPGRADE YOUR REQUESTS
   sudo easy_install --upgrade requests

or as root
   easy_install --upgrade requests

NOTE --upgrade is required.

alternatively you can upgrade to the version I tested today with:
   sudo easy_install requests==1.1.0

if you have installed pip, you can check your version with
   pip freeze | grep requests
I guess RF drops constant columns in poiker1000 so max of 4 features ??
4 is broken because as another test shows, RF won't let me select all the
all the allowed features it says I can. So I'll live with 3 here.
