/***********************************************************************
*
* Name: testn.c
*
* Purpose: Provides statically-loaded (via linker) test processes
* for Round Robin Dispatcher of Module 3.
*
* Procedures In Module:
* test1 - test process
* test2 - test process
* test3 - test process
* test4 - test process
* test5 - test process
*
* Name: Processes test1, test2, test3, test4, and test5.
*
* Algorithm: Each process prints a message to the screen and gives up
* control to the dispatcher using sys_req. Each process
* loops a certain number of times, displaying a message to
* the screen inside the loop. (test1 loops 5 times, test2
* loops 10, test3 loops 15, test4 loops 20, and test5 loops
* 25 times). Each test process eventually requests
* termination. If a dispatcher dispatches a test process
* after it requested termination, it prints a message
* indicating so, and the process starts over.
*
