Starts 60 threads that each sleep for 10 seconds, then spin in a tight loop for 60 seconds, and sleep for another 60 seconds.

Every 2 seconds after the initial sleep, the main thread prints the load average.

The expected output is this (some margin of error is allowed):

After 0 seconds, load average=1.00. After 2 seconds, load average=2.95. After 4 seconds, load average=4.84. After 6 seconds, load average=6.66. After 8 seconds, load average=8.42.
