I've wondered what kind of reliability/throughput would be possible sending data to a single process that writes to a log file (assuming writes don't need to be immediately flushed via using battery backup). I'd want a cancel mechanism that could invalidate a recently written entry by marking the start of it. Seems like it would be very reliable. It could even be made to separate streams to different files/devices. A poor-man's Kafka.
