But why does it want to poll?  I'm wondering whether any of the
async-related timeout changes are...  provoking the "if (update_tick !=
process_tick)" bit to always be true in some cases, and making this
polling behaviour happen infinitely...  or something...

But I've been completely unable to reproduce the error, so I'm just
speculating.
