It's worth noting that Gemini 8 wasn't on its last fallback, as there
were two independent rings of RCS thrusters, and they had only activated
one to stop the roll. But that meant there could be no backup RCS
thruster ring, and the flight rules said that was cause for landing
"with all due haste" (or whatever you call the second flavor of ASAP).

Actually they had activated both RCS rings, but stopped using one ring to
conserve fuel once they were able to re-gain control (from the Gemini VIII
Mission Report).
