A visitor could get a closed connection and no answer when
SWRP_MAX_RESPONSE_TIME_MS ran out about when the answer started: the
write deadline passed before the first byte was written.
- An answer rproxy gives itself has at least 10 seconds to be sent.
- An app's answer that arrives once the time has run out is answered
504.
- Otherwise the app's status and headers are sent at once, before the
body is read, with at least 10 seconds. The exact limit applies to
the rest.
