Message-ID: <20231104092125.10213-7-anton@khirnov.net> (raw)
In-Reply-To: <20231104092125.10213-1-anton@khirnov.net>

This ensures that tq_receive() will always return EOF after all streams
were receive-finished, even though the sending side might not have
closed them yet. This may allow the receiver to avoid manually tracking
which streams it has already closed.
