Maybe you can have something like a wait/pause inside the loop and adjust the wait time depending on the output of the load function described in the link given. Or make your loop such that one instance only gives x% load (again using waits or something), then your main script starts a loop as a subprocess, checks the cpu load, then starts more if needed. I don't know how you can do it such that all cores are at 70% though.
