What is this circuit?

I was looking through some special kwality (my kue key is broken) tubes today and looked up the E92CC. Kind of disappointing when I saw it was a computer tube not recommended for audio, or where hum and microphoney are concerns. However, I noticed this circuit and am curious as to what it is.

Is this just the tube life testing circuit maybe?
 
I guess they expected those old computers to be the end all in computing technology. I've seen parts and chunks from those old computers that used tape. Built like they were meant to last forever.
 
Nasadowsk called it: this is how one builds a latch using a dual-triode tube.

The key is how the grid and plate are cross-coupled to latch into a meta-stable state, with some R||C to clean up the pulse edges.
