When finishing to respond on a stream, a shutw() is called (resulting
in either an end of stream or RST), then h2_detach() is called, and may
decide to kill the connection is a number of conditions are satisfied.
Actually one of these conditions is that a GOAWAY frame was already sent
or attempted to be sent. This one is wrong, because it can happen in at
least these two situations :
- a shutw() sends a GOAWAY to obey tcp-request content reject
- a graceful shutdown is pending
In both cases, the connection will be aborted with the mux buffer holding
some data. In case of a strong abort the client will not see the GOAWAY or
RST and might want to try again, which is counter-productive. In case of
the graceful shutdown, it could result in truncated data. It looks like a
valid candidate for the issue reported here :

A backport to 1.9 and 1.8 is necessary.
