    [platform] Implement delayed tasks in the default worker runner · da66158f
    Peter Marshall authored
    This was unimplemented but is needed for Perfetto which posts delayed
    tasks on worker threads e.g. drain the trace buffer into a file every x
    seconds.
    
    This is implemented by adding a second queue which holds the delayed
    tasks in chronological order of 'next-to-execute'. We use an
    std::multimap for the queue so that we can easily get the next delayed
    task with begin().
    
    The implementation will move delayed tasks into the main task queue
    when their deadline expires.
    
    Drive-by cleanup of the runner destructor which can just use = default.
