The appendix include source code, execute program and output from top
command and Valgrind.
the top_result_before_1_hour is the information got from top command before
executing test program.
after 1 hour performance,  I store the top information into
top_result_after_1_hour.
the valgrind_output is the information from Valgrind:

valgrind --leak-check=full show-reachable=yes ./test > valgrind_output 2>&1

Best wishes.
