I don't think that's correct. Timers currently operate only outside
of AioContexts and that's what we're maintaining. You're saying
make them work only inside AioContexts and add another AioContext
to paper over the hole that's there because we have two nested
event loops. What I'm saying is if don't have 2 nested event loops
(i.e. once Stefan has done his stuff), we won't need the
main_loop_tlg then, and removing it will be easy. What I don't
want to do is have all the worry about breaking things I don't
fully understand by requiring that everything has an AioContext
that uses timers now.
