What is the meaning of the pool.map behavior that is not consistent?

edit

The pool.map behavior that is not consistent refers to the fact that the execution time of different tasks is not deterministic or uniform. This means that sometimes the tasks that take longer to execute may complete before tasks that are expected to take less time. This is because the map function uses parallel processing, where multiple tasks are executed simultaneously, and the order in which they complete is dependent on several factors such as the number of available processors, the complexity of the tasks, and the workload of the system. As a result, the behavior of the pool.map function may not always be consistent and may vary from one execution to another.
