Thanks for the PR! Will this break in previous Node versions? Or has the global lowercase var always been available?

I just checked the docs for some older versions of node... the farthest back I went was 0.4.0, and it was there. Travis shows it passing on 0.10, FWIW. I can't vouch that 'global' has always been there, but it's seems like it's been there for a while.

Actually, the node PR with the fix is informative... "This should be pretty low risk to remove", they say.
nodejs/node#1838

Awesome - I also should have paid attention to the CI checks right on this page where Travis tested it against old versions of Node already ;)

Thanks again for the PR.

Not a problem. Thanks for producing this lib... it's exactly what we needed and has worked great for us.

So very glad to hear it!
