Description

I need to be able to interrupt a list of tasks with a new list of tasks that cannot run concurrently with the first list:

  • Wait for all current tasks to complete.
  • Switch to a new scheduler
  • Finish the tasks in that scheduler.
  • Resume the tasks in the old scheduler.

  • Summary changed from ThreadPool: ability to interrupt a scheduler with another. to ThreadPool: ability to resume a ThreadScheduler without restarting threads

Change description:

  • new method, similar to joinAll, that does not abort threads when the scheduler is empty. Instead, it allows the scheduler to get re-filled and the threads just wait for new tasks.

The test in KernelTest.ThreadPoolTest works correctly so this must be OK.
