Summary:
I was running RN 0.31 on ArchLinux (kernel 4.7), and "react-native start"
was refusing to run on the default (and sometimes required, as I have
noticed) port. I tried executing the suggested lsof command, but that did not
work. Somewhere I found the lsof command I include in this commit, and that
worked (it was a node.js process). So I'm including it, since I found it
helpful.
