I was referring to vl.c's timeout = 10; which makes the select call use a timeout of 10ms. That said, "/* If all cpus are halted then wait until the next IRQ */", so maybe that's why you get slower wakeups per second. I'm still surprised because of the call to qemu_mod_timer in pit_irq_timer_update which should setup at least a 100Hz timer with linux guests (when they don't have HPET available).
