A flesh an bood cooperative multitasking Prolog system
is sometimes tricky to do. We were agonizing over the
last days how we could test our timers and tasks.

Our existing framework doesn't work, since it neither
waits for a timer callback to be fired and to complete,
nor for a task to complete. But its seems its just an
instance of a Promise again.

Turn the test case itself into a Promise, and wait for
it. In Prolo terms, the test case is a success when the
.then() port gets reached with SUCCESS, or its a failure
if the .then() port gets reached with FAILURE or if the

the .catch() port gets reached. Interesting framework
that does just that:, whereby the use assert, to turn
FAILURE into an exception:
