[tor-talk] TBB 3.5 - lot of Unable to connect errors

Does the problem go away if you set 'OptimisticData 0' in your torrc by
any chance?

Bobnomnom claims that there is some kind of issue in how we retry
streams on circuits (which I think was changed by OptimisticData), and
this is getting aggrevated further by a reduction in the Linux kernel
TCP timeout on the exit side.
