Fix Actor::waitUntilIdle (!103) · Merge requests · i4 / manycore / emper

Florian Fischer requested to merge aj46ezos/emper:fix_actor_waitUntilIdle into master Feb 19, 2021

Actor::waitUntilIdle is not sound because currently it busy loops may causing starvation of the Actor it is waiting for.

If emper is compiled with IO we use an AlarmFuture to wait for a second freeing the worker and then check again.
Otherwise we still busy loop but use the new emper::yieldToAnywhere to free the current worker.
