Do not mutate messages used in ServerStream.SendMsg()
When I was writing this code it was not documented that it's not ok to mutate the message after sending it. Docs were added in https://github.com/grpc/grpc-go/pull/5894.
Relates to #393 (closed).
There is code that is mutating messages sent using ClientStream.SendMsg()
. I asked if it's ok or not.
