To have the child waiting on the parent looks like this:

    }elsif($pid == 0){
        # This is the child, it will log when the parent is done      
+                                                                     
+        
        while(!&parentIsDead){sleep(10);}
#       &finalLog($traceFileToLog);                                   
+                                                                     
+        
        &finalLog($traceFileToLog, $initialString);
        exit(0);


sub parentIsDead {
    if(getppid()==1){
        return 1;
    }
    return 0;
}
