I am looking at the advantages of threadpooling design pattern in Embedded systems. I have listed few advantages, please go through them, comment and please suggest any other possible advantages that I am missing.

1. Scalability in systems like ucos-2 where there is limit on number of threads.
2. Increasing capability of any task when necessary like Garbage collection (say in normal systems if garbage collection is running under one task, its not possible to speed it up, but in threadpooling we can easily speed it up).
3. Can set limit on the max system load.

Please suggest if I am missing anything.
