SPDY: fixed possible request hang. Processing events from upstream connection can result in sending queued frames from other streams. In this case such streams were not added to handling queue and properly handled. A global per connection flag was replaced by a per stream flag that indicates currently sending stream while all other streams can be added to handling queue.
