/* test6.c
 *
 * There are two processes: Main and Proc A with rates 20 and 30 respectively.
 * After 5 seconds from the system start, Proc A sleeps for 30 seconds.
 * During that time, Main monopolizes the CPU. When Proc A wakes up from sleep,
 * its Pi value should get updated and we can expect it to monopolize the CPU
 * for some time, till its Pi value becomes on par with that of Main. Calculate
 * how much time Proc A takes after waking up to catch up with Main. Report this
 * value along with the results of test5.c. Compare your results with those
 * calculated theoretically.
