Associating the main loop's timer lists to other AioContexts is really
really wrong...  It is _already_ wrong to run timers in the main
AioContext's aio_poll (because timers may not be ready to run from an
arbitrary aio_poll), it is even worse to run them in other threads
without taking the BQL.

What exactly is the purpose of this series?
