Detailed Description

Process ready task.

Each ready task is paired up with an instance of LogReadyTask which runs before. That is, we know that an instance of LogReadyTask has put the task of interest into the ready queue identified by _taskQueue. We therefore can now lock this queue and process all tasks from the queue in one rush. The task for which we have originally been created for through tarch::multicore::taskfusion::translateFusableTaskIntoTaskSequence() must be among the tasks in the queue, unless some other instance of ProcessReadyTask has already handled it. If this is the case, we are fine. Let's do all the other tasks that are in there and we are done.
