Issue with stream.Close() operations

[RedMarcher]

So 2 questions:

1. For bidirectional streams, does both the server and the client need to call .Close() on the stream to shut everything down?

2. For some reason, I know for sure my server is calling stream.Close(), but my client never seems to receive a err.EoF, and thus it just hangs forever despite the server already having all the information it needs and even exiting out of the specific API call.
