Log:
Ensure that reads outside of propagation block until propagation is
over.  Drop EventLoop service; it was overkill for what's actually
needed.  I'm keeping the dependency on Contextual since Time, IO,
and Signals will all be context.Service classes later.  But the
core doesn't need this service, and this way it'll be easier to
write a C version later, if needed.  There may still need to be
a way to replace the runner to serve in other event loop systems,
but for now I'm treating it as a YAGNI.
