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 ms (the maximum adjustment in qemu_calculate_timeout) you just keep polling but hardly execute any code.
I'll try to post something in the weekend. Paolo
