+Ordering Status and Reads in the gRPC API
+-----------------------------------------
+
+Rules for implementors:
+1. Reads and Writes Must not succeed after Status has been delivered.
+2. OK Status is only delivered after all buffered messages are read.
+3. Reads May continue to succeed after a failing write.
+   However, once a write fails, all subsequent writes Must fail,
+   and similarly, once a read fails, all subsequent reads Must fail.
+4. When an error status is known to the library, if the user asks for status,
+   the library Should discard messages received in the library but not delivered
+   to the user and then deliver the status. If the user does not ask for status
+   but continues reading, the library Should deliver buffered messages before
+   delivering status. The library MAY choose to implement the stricter version
+   where errors cause all buffered messages to be dropped, but this is not a
+   requirement.
