202. Thread pool with a single thread

In order to show how a thread pool with a single thread works, let's assume that we want to write a program that simulates an assembly line (or a conveyor) for checking and packing up bulbs using two workers.

By checking, we understand that the worker tests if the bulb lights up or not. By packing, we understand that the worker takes the verified bulb and put it in a box. This kind of process is very common in almost any factory.

The two workers are as follows:

• A so-called producer (or checker) that is responsible for testing each bulb to see if the bulb lights up or not
• A so-called consumer (or packer) that is responsible for packing each checked bulb into a box

This kind of problem is a perfect fit ...
