It is -icount N which is broken and unfortunately your patch does not
fix it.
The problem is that for use_icount == 1 qemu_icount_delta always
returns 0, and this makes no sense in the iothread case. As soon as the
delta becomes greater than 10

Yes, using qemu_icount_delta directly in tcg_wait_io_event timedwait
is explicit (partially the reason for confusion with my patch).
So the reasoning for the patch is:
With icount vm_timer timers expire on virtual CPU time. If a CPU halts,

I agree with Jan that this patch is not the best solution, if not incorrect.
However, in the iothread, the main loop can

Assuming the VCPU is in the timedwait that Marcelo changed, the global
mutex is free and the iothread will not kick the VCPU.
