Hmm, I'd like to see these as thread-independent sources of async
activation, not as thread-independent asyncs. A timer could be
configured to mark a particular async to run in whatever thread is
current when the timer goes off. Likewise when I/O becomes possible.
Compared to thread-independent asyncs, you will only notice a
difference when there is a thread switch between the time an async is
marked and the original thread next checks for asyncs. If that ever
becomes a problem, we can make a thread check its asyncs before
switching away from the CPU.
