Magnus,
You are doing to have to stop daydreaming about well know technology, if you can master thread technology in either 32 or 64 bit Windows you will have arrived at one of the most powerful techniques for dealing with data, graphics or functionality.
Try a few of these, the executable that starts is the MASTER process or the MAIN process and from that process you can start one or more threads to do any of a multitude of things. You can start a thread as soon as its created OR you can start it suspended and restart it later.
You learn how to use CreateThread() and any of the supporting functions, write the code then test it to make sure it works correctly.
