Chapter 4: About RT programming
The RT kernel uses dynamic memory allocation to free unused memory and assign
freed memory to other processes. Threads within processes use dynamic memory
allocation in the same manner.
For example, some threads periodically need additional memory to improve
efficiency such as a thread that allocates large buffers to speed up input and output
operations. Such threads can release memory for other threads when they
complete, as shown in the next figure.

Threads A and B use memory in the process's memory pool for objects they create.
Thread C completes and then deletes its objects, and releases its memory to the process's
memory pool.
Thread D requests memory.
