I don't know ruby but should that be?

Turns out ENV is actually an Object and not a Hash. It just looks like one.
I've now simplified it to just be the overrides because the default behavior of spawning a process is to inherit all the other vars. So I can't think of why the whole merging was needed to begin with.

I know this is incomplete and some tests still fail, but it's a start. |
RuboCop rightfully complains about using open() to spawn a process. This uses the way simpler IO.popen() method.

I have no idea if this is going to break or not and whether it's an API breakage.
