* A background manager which ensures that all detached task is finished before program exits.
|
|
*
|
|
* Some tasks, telemetry submission for example, prefer executing asynchronously and don't care
|
|
* about the result. These tasks are suitable for std::thread::detach(). However, this is unsafe if
|
|
* the task is launched just before the program exits (which is a common case for telemetry), so we
|
|
* need to block on these tasks on program exit.
|
|
*
|
|
* To make detached task safe, a single DetachedTasks object should be placed in the main(), and
|
|
* call WaitForAllTasks() after all program execution but before global/static variable destruction.
|
|
* Any potentially unsafe detached task should be executed via DetachedTasks::AddTask.
