9+ *
10+ * The system heap by the standard library doesn't check the limit of the heap cerefly.
11+ * As a result, it is not clear how to detect the over commiting memory.
12+ *
13+ * FreeRTOS hepa is considered safer than system heap. Then, the new and the delete
14+ * operators are overloaded to use the pvPortMalloc().
