Now ‘mirai’ futures can be canceled using cancel(), which also interrupts them by default, which in turn frees up compute resources sooner. Map-reduce API such as future.apply, doFuture, and furrr can take advantage of this by canceling all non-resolved futures whenever they detect an error in one of the futures. Also, canceled futures can be reset() and thereafter relaunched, possibly on another future backend.
Now ‘mirai_multisession’ futures relay immediateCondition:s in near real-time, e.g. progression conditions signals by the progressr package.
mirai::daemons() argument resilience is being removed.nbrOfWorkers() and nbrOfFreeWorkers() did not handle mirai dispatcher errors. Because those are integers, these functions would return the error integer value instead of giving a FutureError.
