- `uv_run(loop, UV_RUN_ONCE)` has different semantics than expected.
  When it returns a number `!= 0` it means that there are still callbacks
  to be executed but it doesn't mean they are ready now. So there isn't
  a way to run in non-blocking mode until there are callbacks ready.
- The new implementation is hacking the private ExecutionContext queue
  by using pointer aritmetics to take its value (since it's private).
  Having the reference to the queue, it's trivial to implement a Eventloop
  that tries to not starve any of the two eventloops by using a round robin
  fashion, and avoiding to block until there is anything else to execute.

* Quiet core/test "close multiple times" test

As folks may know better than I, in uTest individual tests are documented
are documented as returning a value, which can itself be validated.
If the return value is not Unit, it is printed out.

Before this PR, the "close multiple times" test was returning the
value of an object, which was getting printed out and adding
something to the log which needed to be figured out as safe.

This PR causes that test to be silent, thereby reducing clutter.

Agreed, this is a nit. I think it is worth fixing because the present
file may serve as a cut & paste template for additional tests as they
are added.

If I can not fix something useful, I can at least remove a small wart.

* Make "close multiple times" return Future

Before the timer was timing out after the test was declared successful.
To preserve the semantics of utest a async test need to return the last
Future to be completed as result
