Explore the challenges of coordinating two Ruby threads to print 'ping' and 'pong' alternately. Understand how busy-waiting works and why subtle code changes can break multithreaded programs due to context switching. This lesson highlights the complexity of thread synchronization in Ruby and compares behavior with other languages.

Ping Pong Program
We'll write a program that will print ping and pong in strict alternation on the console. Our program will consist of two threads, one to write each string. The challenge is to coordinate the two threads to take turns one after another when printing to the console.
We'll use a boolean flag variable to remember which thread ...
