| * grpc *security_handshaker* begins its handshake with data already |
| * in the read buffer of the handshaker arg. This scenario is created by |
| * adding a fake "readahead" handshaker at the beginning of the server's |
| * handshaker list, which just reads from the connection and then places |
| * read bytes into the read buffer of the handshake arg (to be passed down |
| * to the security_handshaker). This test is meant to protect code relying on |
| * this functionality that lives outside of this repo. */ |
