I think this is incorrect.
When a timer is modified, we need to rearm the host timer immediately. We can
not wait for the old timer to fire, or for execution to fall back to the
main_loop_wait. Consider the case where the guest adds a timer interrupt and
immediately enters a tight loop - Quite a common operation when calibrating a
software delay loop. The timer won't be rearmed until some other event
occurs. It the system is otherwise quiescent and you're not using SDL output
it may never occur.
