SSL negotiation failures causing 408 error to be returned

[bpiraeus]

I stumbled across this this morning after talking with some co-workers
about what we're seeing

http://code.google.com/p/chromium/issues/detail?id=85229

I'm wondering if someone @ MS decided IE9 would benefit from the same
speculative pre-connect sockets. If we strip out anything that's not
IE9/Chrome we're left with a pretty small subset of 'other browsers'
which I'm leaning towards considering outliers just by virtue of being <
.5% of the overall error count.
