Generic Thread Pools (Windows Only)

On Windows, you can set up additional thread pools using the Server Manger. Use thread pools to put a limit on the maximum number of requests answered by a service function at any moment. Additional thread pools are a way to run thread-unsafe plugins. By defining a pool with a maximum number of threads set to 1, only one request is allowed into the specified service function.
