QEMU performs a recursive unchaining on the current executing tb when a timer fires. This timer is set by setitimer in the qemu-timer.c. This is what I mean by "interrupt pending". Of course, there are interrupts from emulated devices as well, but i do not know how that is set up, i.e. how tcg_handle_interrupt is called when the devices finishes some work. I hope you can enlighten me on that.
