This seemed pretty bad too, because now you potentially miss up to 2
seconds of messages AND it adds more complexity.

I'm fine with changing things up to accommodate RT, but not when the
result is so obviously worse than before.

In my tests I can't see any latency difference with using raw spinlocks
in random.c. Maybe I'm doing things wrong? But I'm not seeing anything
change...
