Get environment variable w/o killing CPU on linux

[kbrose]

This is an attempt to fix #20.

I do not have access to a Mac, so I cannot check verify that this change does't re-introduce #4.

@kbrose Thanks a lot for your PR! 👍

Unfortunately this re-introduces #4 since atom.getLoadSettings().env doesn't correctly get the PATH on mac. As soon as I find time I'll test this again and see if it's a bug in Atom core or if we can find a better solution that works on linux too.

It doesn't? Do you have a pointer to a discussion about that?

What about atom.updateProcessEnv and process.env?

What about atom.updateProcessEnv and process.env?

Thanks for the suggestions, unfortunately both don't help either 😕
Looks like we're running into an Atom bug here.

Could you test if #29 works for you?
