### Locks We have 3 different things that we synchronize on. #### Http2Connection This lock guards internal state of each connection. This lock is never held for blocking operations. That means that we acquire the lock, read or write a few fields and release the lock. No I/O and no application-layer callbacks. #### Http2Stream
