A timeout issue is one *possible* cause of the errors you were seeing
from nginx.  Of course you know the application better than I do, so,
I'm not certain it was a timeout issue, just a likely cause of the
errors.  Did your Unicorn error logs tell you if there were any
timeouts?

Anyways I'd always put timeouts around any code that accesses remote
services since the Internet is unreliable.  It's also pretty easy to
setup an evil OpenID provider server that can DoS web apps that don't
timeout themselves.
