Future support

Overview

The following sequences shows how futures (which are deprecated) are implemented in order to provide blocking behaviour for a given task.

• Synchronous wait on event set by higher prio context. It is expected that the waiting task is suspended (using a FutureSupport object) and giving all other tasks the chance to process events. Here the context that signals the event is of higher-prio therefore the waiting task will only be executed after the higher-prio runnable has terminated its work.

• Synchronous wait on event set by lower prio context. It is expected that the waiting task is suspended (using a FutureSupport object) and giving all other tasks the chance to process events. Here the context that signals the event is of lower-prio therefore it will be pre-empted on setting the signal and continues after the higher-prio task has finished its work.
