+ Assumption: The test assumes that this program is run under normal conditions,
+ and not when the processor and other resources are too stressed.
+
+ Steps:
+ 1. Fork() a child process. Have the child suspend itself.
+ 2. From the parent, send the child a SIGUSR1 signal so that the child returns from 
+    suspension.
+ 3. In the child process, make sure that sigsuspend returns a -1 and pass that info
+    to the parent process.
