The idea is having a loop that calls the ThreadPool to execute some method, and then block that main thread until all threads are finished.

when there are many threads?

Well, it is, but only if you have kernel development experience and know how to use a technique called "DLL Injection" to hook into the kernel and intercept the calls to CreateProcess. You also can NOT do this in and managed code language, like C# or VB.NET. You'd have to write this hook in C++ only.

Is this going to remain a viable option going into Win64? I know that MS has sharply reduced the ability to hook into the kernel, but don't have the kernel specific knowledge needed to know if this is an affected area or not.
