To use this test also in embedded systems it needs to reduce the memory allocation to avoid the test failing when it check the ru_maxrss field expecting a value close to the allocated one. The ru_maxrss field contains the total amount of resident set memory used, so this field doesn't take into account of the swapped memory. Passing [num] parameter at command line the test is executed using the input parameter as multiply factor instead of 10, that is the default value when no argument is passed.
