In this commit, we make the ping manager sync blocking. This ensures that we don't start the ping timer until after we've actually sent out the ping on the wire. Otherwise, it's possible that if processing the normal outgoing queue is very delayed, that we expire the ping timer before we even send anything out to the remote peer. We also increase the msg size buffer. As otherwise, due to TCP head of the line blocking, we can still timeout the ping sends if we're just waiting for the remote party to receive the ping in the first place after a flurry of sends.
