BTW, what happens if we insert into one queue and immediately get woken up, even before the damn thing gets to the end of ->poll(), which proceeds to call poll_wait() again (on another queue)? AFAICS, apt.error will be set by the second callback and completely ignored. And so will the return value of ->poll()... Sigh... Analysis of that thing is bloody painful, mostly because it's hard to describe the state...
