No it isn't. System_ waits for the file executed to finish before proceeding with your program. Now if the file you want executed is a server program (like for instance Apache) that "never" finished, your program is going to hang indefinitely.
More importantly tho', if your program is ended (for instance by someone killing it in Taskmanager, or an overzealous windows task scheduler that reckons your program "stopped responding") it's going to take the program you've executed with it.
It is not, by the most broad definition, the same as CreateProcess, which actually launched the program in question in a seperate process. Except on Linux, but that's thanks largely to the OS.
