We've been able to replicate once in a VM running Win 7 w/ Chrome.

We've done numerous packet traces, at this point we're fairly well
stumped and are leaning towards it being some strange interaction with
SSL+Flash. The 408s, while not specifically problem, may indirectly
contribute to some behavioral issue that we're still trying to track
down. I would be hard pressed to put this on Nginx, I was, ultimately,
hoping someone had perhaps seen this behvior previously and had some
insight into the issue.
