Sorry, I left this out: If you can reproduce it again, can you

Odd, it is stuck in rb_mutex_sleep based on your backtrace (from
Logger, it looks like); and you can reproduce it on recent trunk.
I'm trying to reproduce the bug, but I cannot. I will let it
run while I do other things...
I suspect the problem is a bug in our deadlock detection
(vm->sleeper (*))
In your code, you have a t0 dummy thread. Is it really needed?
Curious, how many CPU cores and what model do you have?
Can you reproduce it if you use taskset or schedtool to limit
it to a single core?
Do you have a different hardware to try on?
(*) I also wonder why vm->sleeper is volatile, it should not
need to be.
