Bidirectional streaming leaves header messages in mailbox

[davisp]

I haven't done a minimal reproduction of this but it appears that using bidirectional streams leaves a headers message in the mailbox of the process that created the stream. I'm not sure if that's a bug or not even.

Referring to the client, correct?

I wouldn't doubt it. If so it will be resolved when I refactor it to not rely on sending messages to the process making the request. Original idea was to keep it lean and with as few processes as necessary, then build a higher level client on top of it for particular use cases. But I think it is too much of a mess and should simply be a process that the client interacts with.
