WebMay 9, 2014 · A Critical Section always allows recursion within a thread. So does a Mutex. That is by design and cannot be changed. A Semaphore, on the other hand, can prevent recursion within a thread. See MSDN documentation for more details.

The iterative version of the algorithm requires managing a stack of data. This isn’t a performance-critical section of code.
