Producer Consumer Program

A producer thread places jobs in a bounded-buffer, and these jobs are retrieved by a consumer thread.

When initially started up, the program creates a producer thread object and a consumer thread object. The threads then can be started by pressing the Step button.
You can kill and recreate the producer and consumer threads by pressing the Restart button and start them with the Step button.
The Delay and Continue buttons have no effects.
The producer produces 20 jobs, the last 10 of them slowly.
The consumer consumes 20 jobs, the first 10 of them slowly.
