Yes, I have met Andres in real life and I can totally believe that he is that in tune with his system. He wrote that he found this while benchmark PostgreSQL and saw weird load from ssh. He does a lot of benchmarking of PostgreSQL patches.

But I would say it was also luck. If Andres hadn't been benchmarking on Debian Testing (or whatever system he found this on) this might have taken longer time to discover.
