[Nitro] Broken Net::HTTP in ruby 1.8.3+ [slightly OT]

[Rob Pitt]

I think I mentioned this a long time ago but was silly enough to install
1.8.4 somewhere critical again, this fix was sufficient to fix my
problems with this library under the new version so I provide it here in
case anyone else was being given headaches by it.
